Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
For more information about that channel's account authentication functionality, It's best to reach out directly to get the channel going on your Roku. They can resolve the error you are having with the channel login. Please be noted that Roku doesn't manage channel logins or authentication and many channels on Roku are developed and maintained by the channel provider themselves.
We would recommend the following steps to see if it helps you with your issue:
sign out of your channel (if you are currently logged in)
remove the channel from your Home screen
restart the Roku device
add the channel back again
re-authenticate the channel with your credentials
As stated previously, if you are still experiencing an issue with accessing the channel, you'll want to contact the channel provider support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
It has been a week now and I still can't use my xfinity app on both devices. Still doing the sign in death loop. I have spent 6 (yes 6) hours with xfinity trying to fix this issue. Yesterday I was online for 3 hours with xfinity rep. I am waiting for a phone call to start troubleshooting again with xfinity. Just wanted to update you all on what iam currently dealing with.
So not sure what happen. Went and reset (again) the TLC Roku TV this morning and low and behold the logon went through! Had to leave for DR appt so I will try and sign on upstairs on my 4660x2 to see if it will go through as well. Will keep you all updated.
