Paramount Plus errors much of the time

Paramount Plus on my X1 box is extremely slow and annoying to navigate….. every time you hit the arrow to move it may take 3-5 seconds to actually move.

Then once you selected a movie or show it shows “Error.  Something went wrong! Please try again later. error code-“

Sometimes it may work by reselecting but most times not.  No error code is ever given.

Any fix for this?   If not The Paramount Plus subscription is not worth the money.
