Can't buy anything with UnityIAP on IOS (Thai region)

Hello. I have one problem. When I try to buy anything in my app using UnityIAP plugin on IOS (Thai region), I got an exception with strange stracktrace which is connected to DateTime methods.

Exception:

P.S. On other region (US, UK, EU) everything is okay and I can buy anything what I want.
Unity 2018.3.14f1. In App Purchasing package version is 2.0.6. Apple (Sandbox). IAPSecurityException

What version of the IAP Asset package you you using? The latest is 1.22. You need both the Package Manager and Asset packages.

 

IAP Updates window says that I'm using the latest version (1.22.0)
In App Purchasing in Package Manager version is 2.0.6

 

I think this related to Unity fixing localisation in 2018.3. Now Datetime format uses Thai buddhist Calender on thai devices.

 

I have not found any info about it. Can you please provide any link?

P.S. Or maybe unity representative can give some info?

Have tried with 2018.4.2f1 and 2019.1.6f1 and got the same exception!

 

No updates at this time, this is an issue we are looking into.

 

I think it's related to this
https://issuetracker.unity3d.com/is...66.515640864.1560468572-1976000747.1499913666

After I upgraded I noticed I had a lot of culture / cultureinvariant issues (ToUpper for turkish) along with string.Format + DateTime bugs including the one above. Specifically for Thai.

These were "dormant" bugs in my code but when Unity fixed it it caused those bugs to appear.

Hello. Is there any update?

 

Hello. More than two weeks has been passed! Is there any update?

 

No updates, any fixes would expected to go into the next release, likely a few weeks to a few months out if it turns out to be addressable in the IAP package.

 

Problem solved? We are having the same problem.

 

I have mentioned this again to the engineering team, hopefully bump up the priority.

 

Hello! Got the same errors (SignatureInvalid) from Thai users! I'm using the latest IAP and Unity 2020. Unfortunately, I don't have a receipt to attach you.

 

I have ping'd engineering for an update.

 

Dec 21, 2020 now, the issue still exist, mine is on android devices from Thailand, basically non consumable IAP purchases don't work because of date issues, but consumable ones works just fine.

 

Hi @aubreypuan

We have a fix that is undergoing code reviews and then QA validation. Unfortunately, due to the holiday season, most of our staff are on holiday, so it may take a while before it's release, but hopefully very early in January.

We apologize for the inconvenience and will update you when it's released.

 

Thank you for your patience as we investigated and identified the root cause - we found and fixed two issues with Thai locale flows in Unity IAP.

Version 2.2.7 (not yet released) will completely fix this issue.

The first fix in 2.2.6 addresses non-Subscription Products, and only partly addresses this issue.

These fixes improves the stability of Unity IAP. Thank you very much for the clear reports.

 

I just migrated to IAP 3.1.0 from 2.2.4 and I'm hearing that Thai subscriptions are no longer acknowledged on Android or iOS?

 

Where did you hear that, can you provide a link to the article or reference?

 

Sorry for my choice of words, but I'm referring to my own feedback from Thai customers. Since upgrading from IAP 2.2.4 in Unity 2019.4 LTS to IAP 3.1.0 in Unity 2020.3 LTS, every Thai subscriber has complained that it is not restored (item.receipt is null). Bizarrely, they show up in Google Play as repeat orders that cost THB 0.00.

I'm reluctant to blame the code as it's the same code that has worked all year, and no other region seems to be complaining of it. Any insight would be appreciated, as I don't know what to tell them!

 

How are they restoring? I want to make sure they/we are using the correct terminology. Restore occurs when you reinstall the app, they should be receiving ProcessPurchase (and awarded the product) during IAP initialization. Is it only restore that is failing, but purchases are succeeding?

 

Following the sample, I've been checking for valid receipts "OnInitialized". Thai receipts no longer get beyond "item.receipt!=null" where they used to and every other region does. It would help if I could get their item.metadata.isoCurrencyCode to treat them differently in the meantime?

Even if they try to restore manually through RestoreTransactions() the purchase is not processed. I imagine new purchases are also not succeeding, but I have no evidence of that.

 

So receipts are null for Thai users, and non-null for other users? Are you able to get the isoCurrencyCode? Sorry I'm not quite following, that code looks correct. Is it generating an error? Restore is the automatic process (on Google) when users reinstall, please confirm. Your report claims that the initial purchase succeeds. But if they install the app on a second device or reinstall on this same device, then their products are not Restored.

 

My understanding is that an initial purchase in IAP 2.2.4 was successful, but this can no longer be retrieved in IAP 3.1.0. Even more strangely, the attached is all from the same user who appears to "successfully" resubscribe for THB 0.00 every time they try to restore it.

I'd like to revert back to v2.2.4, but I'm getting the impression this is discouraged in Unity 2020.3 LTS as it doesn't even show up as an option???

 

I might expect the image you provided, they are not being charged. Are you hearing this from just one user? Do you have the previous version APK or a previous release on the store you could publish or provide directly to the user? Yes, 2.2.4 does not appear to be available.

 

After upgrading to @JeffDUnity3D unity version 2020.3.6 we are seeing that any DateTime.toString() crashes at
System.Globalization.DateTimeFormatInfo.set_Calendar
With "ArgumentOutOfRangeException: Not a valid calendar for the given culture. Parameter name: value"

It's easily reproduce-able on Android device just by setting the language to Thai.
I haven't been able to test IAPs but I'm assuming it is related...

 

Sorry I don't quite follow, are you using IAP?

 

We are using IAP but what I was sharing above was just my 2cents, as unity 2020.3.6 has a known issue with Thai locale (seems to be fixed with 2020.3.7)

 

Ah got it! Thanks for the heads up.

 

My users have confirmed that changing their device's language to English does indeed fix their issue. I'm currently using 2020.3.1. Is it definitely fixed as of 2020.3.7?

 

My Thai users still have an issue even after upgrading to Unity 2020.3.9 LTS with IAP 3.2.1. They can only proceed in the English language.

 

So your users upgraded to the new version, have you confirmed?

 

Yes, a handful of Thai users grabbed the very latest version and reported the same crash on Android (Unity 2020.3.9 LTS with IAP 3.2.1).

 

This issue still exists in In App Purchasing 3.2.3 - Unity 2020.3.13f1+. It has cost us hundreds of man hours to debug and we have lost a lot of paid users because of this issue.

 

Hundreds of hours? Do you mean it works sometimes, and other times not? Otherwise it would be 5 minutes to test with the proper device, hundreds of man hours could purchase the equivalent of a few test devices! Regardless, we are investigating, it does not look specific to IAP but the system API calls we make, we are looking for a work around.

 

I have the same problem，

Using datetime.now.toString () will cause an error when the Android device selects Thai language
Unity version： 2020.3.16

 

Are you using Unity IAP? What version?

 

• No, it's just an empty project

 

• I found a fix for this issue in Unity Version 2021,but there is no LTS version for 2021

 

Sorry, you are in the IAP forum, not related to your issue.
