I haven’t read all the posts here. Just so much on this:
I have had an Amazon Developer account for many years and also published some of my apps on Amzon. Then came the horrible Amazon “Underground” and I put all apps offline. Then came the Amazon App Store and I updated the apps and offered them again, at the same prices as in the Play Store and the Apple App Store. Result: very few downloads, it is actually not worth it.
And yes, you also have to store a lot of personal data there, including tax data etc. I wouldn’t do that to myself anymore.
My apps in the Amazon App Store are built with AI2. I did only a few changes to the Play Store versions. So the APKs are almost the same as in the Play Store.
