@telent Like @cccam said, Google is banning apps that serve as alternatives to its services. F-Droid and Aptoide are alternatives to Google Play that Google can't control -> banned. NewPipe is an alternative to Google's YouTube app that even doesn't show ads -> banned.
Thanks to reproducible builds it will have the same signature as the versions from the play store and the the author's own #fdroid repo, so you can update from there.
