Steam will go live first and it may be a few hours before Apple and Android are running latest. The "home" feature from the title screen will not work until the server is also updated.
Summer items will come soon, and the game has a new title screen and terms of service section to bypass before playing. (This is in part due to new laws in the EU - Minimum age for EU players is now 16yrs old.) Terms of service will also not work correctly until server is restarted a little later this morning.
