Still not able to log in via the Android app as is. Will try some more trouble shooting.
Edit: Additional Steps Taken.
Changed LB Forums password
Uninstalled Tapatalk, reinstalled. Did not sign into Tapatalk, loaded LB Forums, attempted to sign in got a error that was just a string of letters and numbers vs. when signed into Tapatalk I will get a unknown network error has occurred.
Attempted again by signing into my Tapatalk, un-followed LB Forums, re-followed, attempted to sign in and got same error message unknown network error as originally posted.
Things I could have tried but didn't yet:
Restart my phone in between each step.
Attempting on a Android Device that I have not used with Tapatalk before.
