Hi, I just upgraded my vbulletin 4.0 forums with the new version and for some reason I can't logon using tapatalk from my android now. When I revert back to version 3.2.0 it works. I can't figure out why the new version just won't work. When I run a test it says newer version installed but then logon credentials fail. When I go back to 3.2.0 it works fine. Any input appreciated.
