Google Account automatic sync issue

simone.mantovan

I've tried everything, but about one month ago, sync of my google account stop to work (no errore displayed, simply syncronization is stopped, even if the automatic updates option is checked); I've tried to clear the cache data of the account, rebooted the phone, downgraded gmail, resetted the phone, reinstalled the ROM (both official and unofficial); I've tried also a differente google account, but without success.
I looking for help in debugging and solving this issue; hoping that is not related to my Umidigi S phone.

Thanks.

P.S.: please forgive my english.
