Could it be related to the update of Google Play that was installed yesterday on my device?
On a 2nd device, I use Google Play with version 2020.04.18184 which is still working.
On the tablet with the session expired issue, there is 2020.06.19383 installed since yesterday....
@CapitalGames: Could you check your API, please
I'm not sure that it would be. I first uninstalled all updates for google play and that didn't work. I then uninstalled it completely and did a clean re-install.
I am having the same issue (S10 mobile, google play, game center). Since then I have downloaded the latest android security update, deleted and reinstalled the game, reset my phone. Also called support, which didnt get me any further than where I am now.
I spoke with Google yesterday, and they had me uninstall all updates, and it didn't fix anything. They did everything in their power from their end, and couldn't find a solution
