@chrisb55- There's no need to get testy with some one that's giving of his time to try to help a stranger.
There are lots of people posting lately with the same complaint.
It's not readily apparent to most that each channel provider, like Paramount+ in this case, creates and maintains the specific version of their app that runs on the Roku system. The only channels that Roku maintains are their own The Roku Channel, the Roku Media Player, and several Roku information channels. For everything else, Roku just provides the platform on which they run.
Because each platform (Roku, firestick, etc.) has to have its own custom channel-provided version of the channel app, it's not unusual for one platform to exhibit a problem when another platform does not.
On Roku, a "remove channel app / restart Roku / reinstall channel app" process (don't skip the "restart Roku" step) should get you a complete installation of the latest version of the channel app. This can fix things if the problem was caused by a corrupted, out of date, or incomplete installation of the app.
If the problem then persists with that channel while other channels work without a hitch, it generally means there is a problem with the channel-provided app that only the channel provider can fix.
