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.
I think this might be a generational issue. I can sign in and get success on the website for History channel and amc but the roku doesn’t update. I say generational because I put the question to a social media page and one guy said he has a problem with his older Roku TV but not on his new Roku standalone. Others did not have a problem with their newer roku.

History v 2.2 build 6 AMC v 2.0 build 37
Note that I have no problem signing in and using the iOS versions of these channels apps.
