How do I fix 'Login failed' and 'Fatal error' when streaming Paramount+ on a new iPad?

I have a new IPad and it is up to date. The Paramount plus app shows login failed when I try to log into. When I re-boot the iPad it allows me into the app to select user, but then I get either a fatal error or the video is not available try again later. When I log out and back in, I get login failed. I have an IPhone which is linked to my cloud account and there is no problem streaming Paramount plus on this using the app.
