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.
The Cartoon Network app doesn’t Start up ... I select the channel and it load for a bit and then it goes back to the roku home .... I tried updating and restarting my roku and I still haven’t had any luck ..
We would recommend reaching out to Cartoon Network 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 Cartoon Network 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.
Same issue here, with Frontier. The channel worked at a limited capacity before logging in to tv provider (frontier). Now channel starts to load and, once a brief view of a skewed home screen pops up, the screen immediately reverts back to the roku home screen. This is the third channel that this has happened with, not including the channels "no longer supported" (e.g., hulu, espn).
