Does the issue only occur on Paramount Plus or across other channels installed on your Roku device?
Have you tried removing the affected channel Paramount Plus and then re-install again? If not, we suggest starting there. In some cases, removing the affected channel and then re-installing it may help. Restart your device before re-adding the channel back in to ensure the process is successful. We recommend doing this through the Settings menu by navigating to Settings > System > Power (If there is no Power submenu, proceed to the next step.) > System restart.
Could you tell us more about the issue you have with the Paramount Plus channel? Do you encounter any error messages? Are all the other streaming channels operating normally? How long has the issue existed?
