When I try to log into the FIOS TV app, I get an error message that says "Authentication failed" an Error Code of 9-6-23-302-100. I've twice changed my password, deleted the app, re-installed the app, and tried to log in with the new password. Each time I get the same error message.
Customer service has thus far been only able to recommend the password change-app deletion-app re-installation process, which hasn't fixed the issue.
Any recommendations?
