Hi! My ll app keeps crashing and won't go pass the log in bonus screen. I didn't set up a new id and password so if i uninstall and reinstall the game my account will be gone. My question is when I request help from klab and they send an authentication code can I use that code on a different device? I have the account on my phone but since it keeps crashing can I install the game on my tablet and enter the authentication code there?
