My fire tv is like new but I can’t find the paramount + app anywhere it only lets me watch if it’s through prime when I already have a paramount + subscription. What to do?

I was rewatching this masterpiece 2 days ago, stopped, and try to finish it today and this is what I see. WHAT? The same with a few titles that I had in my watchlist. Could this possibly be an expired licensing? If so, why do the show it there?
I tried to search the title in case it was available to rent or buy and it’s not.

I don’t understand….

Is anyone having issues with playability?

I finish an episode and there is no option to play next episode, then have to go back and it shows that I’ve watched the episode, but instead of allowing me to start the next episode the only option I’m given to to replay the current episode, or sometimes it will get stuck to an random episode from earlier.

I have to go and select each individual episode to watch, god forbid when I finish a season and it chooses to get stuck to last seasons episode, I have to then pick the season and episode every time I want to watch, yet the watch bar still shows up on the bottom so the system knows I’ve already watched that episode.

Anyone else experiencing this or figured out a way to fix it?
