I heard they're having some kind of Facebook login issue. If you're only logged in through Facebook and not LINE, I'd wait for them to fix it. I'm not too familiar with the Facebook login, but if you're logged in to Tsum Tsum with LINE, all your game data is tied to the LINE account. So even if you delete or switch devices, your Tsum data will still exist as long as you remember your LINE account info.
