App ID: amzn1.devportal.mobileapp.202e6db4940343a2b87070b2ebe87384
IAP ID: mescape.unlock
I'm trying to send an update to my app but it was rejected again due to failed IAP.
It is 100% issue on your server side.
1. Everything works in sandbox test environment.
2. Yesterday it failed In live app testing, but today with the SAME code and no changes it WORKS flawlessly.
After that I've sent it to production but again got rejected.
PS. R8 and other Proguard related stuff doesn't apply here because my gradle is 3.2.0 and I disabled everything related to that.
Also as I said, yesterday LAT gave me failed purchase, but today it worked, so again it is 100% issue with amazon servers.
