Since this app helps a lot, I happily donated.
Unfortunately, even with Amplify and disabling services & listeners, Google Play Services still eats lots of battery and behaves nasty (re-enabling stuff I disabled). So I disabled it completely. This caused Play Store to stop working, so I disabled it too, and I manually enable them only when I manually update apps.
This caused Amplify to not recognize the donation and disable features.
Couldn't the app store internally it's donation state after checking once? This would fix the situation, and others (Greenify etc.).
Please consider this. Thanks.
