I found a bug with AppGameKit v2.0.21 (Confirmed by damothegreat in this
post)
These are the settings I have used exporting an APK for Amazon. I have tried it on 2 PC's using both the TGC downloaded AppGameKit and the Steam version. And every time I get this error.
The same settings work ok to output for the google store; and according to damothegreat, it works ok if you change the orientation, but sadly I need it to be portrait for the apps I want to publish to Amazon.
I hope this is a simple fix for you, and thankyou in advance
