The difference between the releases on the PlayStore and the releases on Telegram/DuckDNS are that the PS version is a release build (this is a slight difference in the format) but the Google Feed integration requires the client app to either be a system app or a debug build. The PlayStore however only allows release builds to be published (for obvious reasons) this requires us to move the feed integration stuff into a second (debug) app which has to be installed from outside the PlayStore.
