My app has login with Apple and Google. Also, it can be used with no login, in which case, no favourites.
Sign-in with Apple works with Adalo Previewer on Desktop and added to Home Screen iOS and native iOS.
Sign-in with Google works on Adalo Previewer on Desktop and added to Home Screen iOS, but only a small “G” icon block appears on native iOS, and it is not clickable. The Google component is not part of a group.
