wrote to support. no reply. the game does have its own problem and the game should have chat when asking other people to join the game. a lvl 2 player can join the fight with a high lvl player and the lower lvl player joined for joy ride..something is not right with the game. i played the game on two difference platform and both sync to google account but it always have issue that one of the platform has an older saved game and is unable to restore the latest backup
