Same issue for us.
Boxer hasn't updated and this text shows when Boxer is opened.
unfortunately boxer is in an unusable state.
Force Kill
Wipe and Restart
Only workaround so far is to have the end user delete Boxer and reinstall.
I just had the same issue. Stopping the app and clearing data (not just cache) allowed me to make it usable again, without having to re-install. I did have to go through the Boxer initial configuration wizard again.
