Hi @Hong,
Thank you for posting here in the Roku Community!
What troubleshooting steps have you already taken to try to resolve the issue? Have you tried to remove the Paramount+ channel and see if it helps? If you haven't tried it yet, you can remove the Paramount+ and re-install it. To ensure the process is successful, restart your device before adding the channel back in.
We would recommend doing this from the Settings menu by navigating to Settings > System > System restart.
Keep us informed on how you're doing.
Thanks,
Anjelie
