Thanks for posting in the Roku Community!
In some cases, removing the channel and then re-installing it may help. To ensure the process is successful, follow the steps below making sure you restart your Roku device before adding the channel again.
-Remove the channel: Highlight the channel tile on your home screen and press the Star button to open the options menu. Select Remove channel and confirm.
-Restart your Roku device: Restart the device from the settings menu. Go to Settings > System > System restart > Restart.
-Re-install the channel: After your Roku device restarts, visit the Roku Channel Store and add the channel again.
