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.
This recommendation actually made the problem worse. This is definitely a Roku issue because there isn't a problem with my Apple TV. When I was able to log in, it was trying to get me to pay for a subscription I already have.
I have a 4670. Couldn’t log on to the Apple TV+ app either through phone or on device. I just cleared my cache (home x5, up, rewind x2, ff x2), waited for Roku to come back, went into the app and login worked. All logged in now. Give it a try.
all of that BS has been done multiple times. It does not work. ALL of my info is correct. If there were no problems with the roku app no-one would have this issue. It does not even allow me to sign in to the roku app via a mobile device. firesticks work, mobile app works, samsung app works - roku app does not work
Try removing the channel from the Roku home screen by navigating to the channel tile, pressing the * key on your remote and choosing 'Remove channel'. Then restart your device from Settings>System>System restart. Once your player starts up again, add the channel back once more.
If the issue remains unresolved, I'd recommend reaching out to Apple TV directly to report the issue and request additional support. Many channels on the Roku platform are developed and maintained by the channel provider directly, and they'll be able to best assist. If other channels are working correctly, and you only experience this issue on the Apple TV channel (app), that is likely an indication that the issue lies within that particular channel. In these cases, the channel provider will need to investigate the issue in order to help resolve it.
