Bug Codeless IAP fail to initialise on live production app, works fine in editor and shows fake purchase

As the title suggests

a) Unity 2020.3.47(LTS) + IAP package 4.9.2 on Android fails in a live app in Google Playstore. (tested with monitor.bat)
b) on another instance Unity 2021.3.27(LTS) + IAP package 4.9.2 on iOS submission rejected due to "Remove button" not doing anything. With this I have no error log yet, but still both do not work and are set up correctly following documentation.

Can someone please look into this. Thank you.

 

?

 

Anyone else experiencing this issue ? I ended up manually coding the IAP system, through sample scripts provided with IAP package. Can someone verify that Codeless IAP is broken ? In App Purchasing 4.9.3

 

I've noticed, in live app (android), that my codeless iap (4.9.2) stoped showing up prices and (new) iap buttons stoped functioning... in 4.9.3 also. (Everything was OK, and I did not touched the IAP until...)

 

Yes the button does nothing when pressed, even though set up correctly following the Doc's

 

?

 

With this I've noticed that Event's fields on my IAP buttons became empty somehow... (same on IAP Listener gameObject too)



So, I added methods back from my fulfilment script, with some adjustments to it, so they can appear in dropdown menu.





My simplified (for the purpose of an example) fulfilment script:

Code (CSharp):

1. using System;
2. using UnityEngine;
3. using UnityEngine.Purchasing;
4. using UnityEngine.Purchasing.Extension;
5. using UnityEngine.UI;
6.  
7. public class IAP_Fulfilment : MonoBehaviour
8. {
9.     public string _failureReason;
10.  
11.     public void OnProductsFetched(Product product)
12.     {
13.         if (product.definition.id == "25_GEMS")
14.         {
15.             GameManager.instance.price_25 = product.metadata.localizedPriceString;
16.         }
17.     }
18.  
19.     public void GrantGems(Product product)
20.     {
21.         if (product.definition.id == gems25)
22.         {
23.             GameManager.instance.gems += 25;
24.         }
25.  
26.         _gemsText.UpdateGemsText();
27.         GameManager.instance.SaveGame();
28.     }
29.  
30.     public void OnPurchaseFailed(Product product, PurchaseFailureDescription failureDescription)
31.     {
32.         if (product.definition.id == gems25)
33.         {
34.             _failureReason = "" + failureDescription;
35.         }
36.     }
37.  
38.  
39.     // METHODS FOR IAP LISTENER EVENTS
40.  
41.     public void OnProductFetched(ProductCollection products)
42.     {
43.         Product product;
44.  
45.         product = products.WithID(gems25);
46.         GameManager.instance.price_25 = product.metadata.localizedPriceString;
47.     }
48.  
49.  
50.     public void OnPurchaseFailed(Product product, PurchaseFailureReason failureReason)
51.     {
52.         if (product.definition.id == gems25)
53.         {
54.             GameManager.instance.notes[7] = true;
55.             _failureReason_1 = "" + failureReason;
56.         }
57.     }
58. }

I'm saving the product price to GameManager.instance cause my Shop "page" not appearing on the start of the game...so I pull those prices back from GameManager.instance, when user opens the Shop page...



Not sure for 100% if this is the right way for Codeless IAP, cause I'm still new to gamedev... but that's worked for me.

 

I have removed fulfilment methods from IAP buttons event's fields OnpurchaseComplete and OnPurchaseFailed - it caused to run this methods twice... (one call from the button and one call from the IAP Listener)

 

And this fixed it ?
