New update 24th March – game won't open!
Since this update screen starts up and logs in, then that's it - reverts to home screen on my I-pad so unable to play! Ironic when the update claims to improve load time and beat 'pesky bugs' plus there is a new chapter Gravity Grove. Hope others can access this and tell me what I am missing...
Just checked iPad for software updates and realised had yet to install iOS 9.3 so thought that's probably the answer. Now installed but problem remains as above.
