[Resolve]Unity iap and European Strong Customer Authentication (SCA) / Interrupted purchases

We recently got an email by apple on Strong Customer Authentication that will be active on December 31
This triggers an Interrupted purchases. I have tested our app and a blank app and it not working.

The purchase flow stop a step 9 here of section Test an Interrupted Purchase:
https://developer.apple.com/documen...g_in-app_purchases_with_sandbox?language=objc

Here the paste bin of the log:https://pastebin.com/SBBLsQxF

I have debug a little bit the file UnityPurchasing.m Especially the paymentQueue function.
Only SKPaymentTransactionStatePurchasing and SKPaymentTransactionStateFailed seem to by returned

I found a similar issue here:
https://forum.unity.com/threads/solved-ios-iap-flow-breaks-if-user-needs-to-update-billing.410107/

Does anyone have info on that?

On our app
We are using unity 2019.4.14
The package version is 2.1.1
and the plugin version is 2.2.2

On the blank test app
We are using unity 2019.4.14
The package version is 2.1.1
and the plugin version is 2.2.5

Resolve: I just created a new sandbox account and it worked.

 

Yes I tested with extensions.GetExtension<IAppleExtensions>().RegisterPurchaseDeferredListener
The same thing occur. Here the log.

 

Yes if i buy without Interrupted purchases it work as expected.
May I add I'm testing on xcode simulator so the test flow is a bit different.
https://developer.apple.com/documen...sting_in-app_purchases_in_xcode?language=objc The flow stop at step 6 of "Test an Interrupted Purchase" so I do not even see the transaction in the Xcode debug windows

My initial test were on testflight I use the simulator for faster iteration.
Thanks

 

It does not work more on device. RegisterPurchaseDeferredListener is not called either.
Here the log

 

Yes step 8 go as expected. I can do step 9 but step 10 never come. I never receive SKPaymentTransactionStatePurchased

 

Thanks I will test with that.

 

Nope not working here the log.
New was tested with 2.2.5
Old was tested with the iap version in the sample
I tested with unity 2019.4.14

I tested with a subscription purchase because we do not have consumable.

What was your step and environment?

 

It dosent work either.
Here my step:

1. Open the project with unity 2019.4.14
2. Update asset database
3. Update unity iap
4. Change the subscription product id to ours
5. link unity service
6. change Bundle id
7. Build
8. Clicked play on xcode
9. Buy subscription
10. Failed

Here the log.
My colleague will test on his mac.

Edit: I tested initially with the codeless sample. This test was with the other sample

 

Yes I was testing with our apple store app that is already published.
The package version is 2.2.1 and the plugin is 2.2.5
I build directly on my ipad.

Edit: my colleague tested and it does not work either.

 

Can you enumerate your exact step from the sample download to buy success?
Maybe you could send your log and video that could help me debug on my side?

It would really bother us to create a new subscription product because we have a big user base.

 

I could create a completely different app for testing but we want to be sure it will work on our app and existing subscription product. I will test on an iphone. And see if I can test on a blank app.

 

…It worked we created new sandbox account and it working now thanks

 

For me I only see this window after acception Terms & Conditions which says "Terms and Conditions of Apple Media Services". I need to press the home key to get rid of it end then nothing happens.

Using Sandbox user and app is published already a year ago. Just trying the Interrupted Purchases.

Is it intended that this window doesn't have any accept buttons?

 

I'm testing on an iPad Air 2.

So the dialog should normally behave different, yeah?

 

I can scroll but everything's blank. Ok, thanks for the info!

 

This has happen to me too but on iPhone 7 plus with iOS 13.5.1. It seem to be a bug on apple side. Maybe older device do that

 

Our publisher already told that it might be related to iOS 12.x, but I can't update with this old iPad. Anyways, thanks so far

 

1. Creating new sandbox account helped us, too. With new account all works as described in Apple docs.


2.

This happens for us on some devices, and we didnt found a way to fix this. So we take another device and test on it.

 

I've just tried this and it works fine for me, but why isn't the IAppleExtensions purchase deferred listener fired if this is deferred purchase?

What are the conditions for that to get fired?

 

That's good to know.

 

Is there any way to know anything about the initial fail so that you can maybe show the user an alternate message when it's an interrupted purchase? I can't see that there is.

 

An OnPurchaseFailed event gets fired. You even said so in your post above.

 

I have tested it myself (in the sandbox). We show a message to the user when a purchase fails.

 

My understanding is that this similar to Ask to Buy. Have you seen how that works live?

 

Yes, I had the deferred listener set up. It wasn't fired.

Just to confirm. OnProcessPurchase is called for Ask to Buy? DeferredListener is just an extra event that is fired too.

 

So, just to confirm. The expected solution is to wait after a PurchaseFailed for some amount of time and see if ProcessPurchase happens? Is there a difference between the PurchaseFailed here and one where the purchase actually fails (where we would want to show a message to the user)? I am trying to support SCA in our app, and the user will get a failure message even if everything is working correctly as it stands.

 

Hello, I am having a similar issue right now.

Using the IStoreListener, we don't receive ProcessPurchase callback after an interrupted purchase on iOS. You can find the related logs inside the logA file. Apple only notifies failure to purchase, then unity updates transactions and nothing. But if I move the application to the background and refocus it, unity updates transactions again and receives process purchase callback and the purchase is rewarded. Logs for this are included in logB file. This essentially forces the user to either unfocus and focus the app, or close and reopen the app.

Is there a way to manually trigger the action that starts UpdateTransactions process and eventually invokes the ProcessPurchase callback?
