While in game I switched the location of, whatever in the "Profile" settings, then I went back to my game and then tapped the back button to show the settings/menu area... to which the app crashed... Now I am unable to launch the app again... I have not tried restarting my phone, so that might help... but no guarantees.
I would upload a log file but I am not sure where it would even export a log file.... But it doesn't.
Uninstall and reinstall to hopefully fix the reoccurring crash. Also note crashes are automatically logged and sent to Mojag for further investigation.
