Cannot synchronize after resetting the game (stuck at 0%)

I’ve been having connection issues for past 2-3 months, i’ve tried literally evrything, and nothing helped, so as last idea i decided to reset the game’s data through win10 app menus.
Now i am stuck at synchronizing data at 0% and i dont even get to play my game anymore.

edit: i forgot, i dont know why it took that long, and why it was at 0% for about an hour, but after a few hours in the background it actually synced
