Having Issue with the Paramount+ App

I'm having an issue with the Paramount+ app on my Roku devices and the Roku TV that belongs to my brother where when you play an episode of a show (any show) it just continuously loads the episode and stays on the loading screen and will not play what was selected. I've tried all the usual things - restarting the devices, unplugging them even for 10 seconds, and uninstalling and re-installing the Paramount+ app to no avail. It is still not working and has been this way for nearly a week. Has anyone else experienced this? Does anyone know of a way to fix this issue so I can resume watching Paramount+ as normal?
