As others have stated, the Paramount + app on my Firestick is awful. It "forgets" where I was in a series. I regularly get freezes and the rotating wait arrow. Sometime it will stop in the middle of a show with an error message. While it is possible to watch the content, it is just aggravating when compared to every other streaming app I've used. The strange part is P+ made themselves the home of Star Trek. For that audience the need to be the leader in user interface, not the industry laggard!
BTW. — After typing this I see this wants proof of purchase and photos. Really? I have better things to do then take photos of TV screen error messages and route around for proof of purchase.
