iOS 14.5.1 seems to have fixed the issue for some
if you can, update your iPhone/iPad to 14.5.1
I have literally tried everything from deleting apps to wiping my tablet and starting fresh. All trackings are on. Many of us are having the same issue. After some digging I have figured a communality. Sims Freeplay has been removed from the apps and websites section under Facebook settings and there is nothing to link it back.
I had that issue as well at first where I couldn’t access the game. You need to by-pass the log in portion. If you have saved your game to the cloud, then delete the game, reinstall and by pass the log in. You will not have access to neighbors aka the party boat, but you will still be able to play the game. Took me two days to figure this out.
