Any more suggestions for this - I'm having the same problem (link successfully launches the app but then just sits and does nothing at the menu screen)
I've tried whilst app is both open and closed, using force stop to make sure it's not running in the background, deleting and reinstalling the app, restarting phone, nothing works...
A friend has used the same link successfully, so the game should be there
It just opens the app to main menu, shows a little lagging circle in the center of the screen whilst it logs me in, and then sits there.
Any ideas would be appreciated - really would like to try this out
