Yes it started last night just before midnight. I was eventually able to get on after like 5 tries. I did get on the first time this morning around 9, but it kicked me out to the opening screen soon after, and ever since then every time I've tried to get on it's been stuck on the Synchronizing message until eventually it gets to the "Cannot connect to server" and then start all over again. I've shut down and restarted the app multiple times, even shut down the tablet entirely and rebooted, still no go. Wifi works fine. Every other app works, just Tapped Out not working.
