IAP purchase fails on some iPad and not on others.

Some players are writing to me that Apple has charged them for the in app purchase but it is not activated. One has even made a video: it puts its user to pay, but the iOS pop up does not come out “the purchase is completed successfully”.
In my iPhone and iPad always going well, and many other users going well too, because they are sending records at the payment missions in Game Center.

My client has an iPad Pro 2nd gen with iOS 13.3.
In my iPad Air 2 and iPhone 7 plus I also have iOS 13.3 and it’s going well.

I am using IAP Button.
Yesterday I updated to see if the latest version of IAP fixed it, but the client says that it still does not work and that he will put a negative review.

My game is this:

What could be failing?
Thank you.

The dialog that you refer to is a system dialog that we have no control over. Are you able to reproduce? From your description, it sounds like it happens every time for the user, so should be reproducible. It may be an issue with that version of the iPad, but would need to confirm. Is is only this user having problems? If not, please try to find what the users have in common.

Thank you very much for the reply. I am asking the device to those who have written to me. The iPad Pro 2nd gen client has told me that it has been jailbroken, could that be the cause?

I would say yes, but look for reports from others.

The other user who wrote me with the problem has an iPhone 6S with iOS 13.3.1 and has not jailbroken.
A third user wrote a review with the problem but I don’t have his email.

Are you using an IAP Listener in your game? Can you share a screenshot of your IAP Button properties in the Inspector, and also the code that you call for a successful purchase and a failed purchase?

And the code in AllMissionsEnabled is very simple:

public void AllMissionsEnabled()
{
MainClass.GetComponent().BuyAllMissions = 1;
MainClass.GetComponent().SaveData();

Debug.Log(“All missions enabled”);
}

For a failed purchase I did not put code, I should have put something, could give me a hint.

I am not using IAP Listener, just the Codeless button.

It’s a non-consumable purchase, I don’t know if I have to check the “Consume purchase” box.

Thank you very much for the help.

And I trust you’ve tested all your product purchases yourself, in TestFlight and with an actual credit card. You are not handling the Purchase Failed case, you’ll want to make sure to do that, just alert the user that there is a problem with the purchase and it didn’t go through. And you’ll want to ensure you are using a Listener if your IAP button is not on your first/opening scene. However, I might recommend instead that you consider Scripted IAP instead of Codeless IAP, it’s much more flexible, and you don’t need a Listener. In some ways, it’s easier than Codeless. There is an example of both types here, the second one is Codeless and has a Listener. https://discussions.unity.com/t/700293 and more info on IAP on iOS here https://docs.unity3d.com/Manual/UnityIAPAppleConfiguration.html

Finally I used Scripted IAP instead of Codeless IAP and the problem has been fixed, two of the customers have changed their rating from 1 star to 5 stars. Many thanks.
