Problems arose ahead of the release of the my game.
“Your app is using an older version of the Google Play Developer API. As of December 1, 2019, version 1 and version 2 of this API are no longer available, and calls to these versions will all fail. Please update to version 3 before this date.”
I received the above warning.
I am using Unity 2018.3.0f2 version and I am using Google Play Game Service (0.9.53) and Unity IAP (1.23.0).
I think it’s probably a problem with Unity IAP.
Another hypothesis is that it may occur in receipt verification.
How do I update the Google Play Developer API?
Also, where is the Google Play Developer API used?
I am not sure how to solve this problem…
If you know how to solve this problem, please answer.
Thank you.
Opinion? Sorry I don’t quite follow. Unity IAP does not use the API. If you are using a separate API to check the receipt, that may indeed be the source.
