The iPad app still crashes a lot.
You cannot exit out of a game to view the main screen without a crash.
There is no background mode. If you go to another app (e.g., iMessage), there is no way to get back into TS without it rebooting the app from scratch. This involves splash screen, main screen, loading, etc. Or it will crash... In general, it's quite unresponsive. I understand that this might be a Unity bug, but it would be good to get the issue acknowledged.
One more bug that is really annoying: autocorrect is not turned on for the chat. You have no idea how useful autocorrect is until it's not there.
