Good morning,
I think I've covered the question. I play on a tablet with Android 8.1. Following server connection problems (no more bonuses, updates), I noticed that PlayStore was no longer functional. I followed Google's recommendations which didn't improve anything, on the contrary. I also browsed your help center without a suitable solution. The only option is to factory reset my tablet. But I can't save my progress because I can't connect to the account (and I don't use Facebook): I still have a server problem (the date and time are good and the wifi is ok). I checked everything and read a lot of help pages. How to do ? Do I need to copy some files to restore them later?
Looking forward to your help,
Sincerely
