The app was removed from the Google Play Store because it contains the REQUEST_INSTALL_PACKAGES permission which it uses to auto-update.
Unfortunately, as per Google's rules, I cannot re-upload the app unless I remove the feature :
The REQUEST_INSTALL_PACKAGES permission may not be used to perform self updates, modifications, or the bundling of other APKs in the asset file unless for device management purposes. All updates or installing of packages must abide by Google Play’s Device and Network Abuse policy and must be initiated and driven by the user.
