So I got my username changed last night, but now my phone doesn't want to cooperate. You go to the main page with all the forums listed, choose the org, it says login attempt failed (expected), gives you a spot for a new username and password, but it will only let you select & type in the password field. Won't let me change the username. Only way around it seems to be to uninstall and re-install.
I don't get on the forum that much from my phone, but usually when I do it is cause the truck broke down and I'm not near a computer. So would be nice to have working.
