Since others are experiencing this issue @bhaktaboy, it sounds like a bad update (like what happened with Max a while back), which I guess I was able to avoid since I rarely use my older Express model, and the only way this can be fixed is to wait until Paramount Plus can resolve this with a newer update that patches this (unlike a newer update that doesn't) if my prior suggestions don't help. Unless you're subscribing to Paramount Plus on the Roku Channel and not directly with the Paramount Plus stand-alone channel app, this isn't a Roku issue else I'd be experiencing this glitch as it seems to me to be a Paramount Plus update issue (through Paramount) to either newer Roku Express models (including your LE) or to all Roku devices that had this problematic update.
Unfortunately, no matter what platform you're on, channel glitches happen from time to time. I have found that most streaming services never seem to be all that helpful on the front end, so calling them usually is a complete waste of time -- especially after others have already called them, but they do always appear to resolve the issue after a while.
Since this isn't affecting all Roku users (much like what happened with Max), this unfortunately may take longer to resolve, but since it has been a month, it may resolve itself sooner rather than later. (Yet once the Max issue was resolved, I was still experiencing the glitch until I removed Max, restarted my Roku, and then re-added that channel, and so far I haven't experienced it again.)
After thinking more about purchasing a different streaming device, I wanted to add that the problem with doing this is that these issues can potentially exist across platforms (and the Max glitch happened across platforms), so even with a different device -- the rewind issue could potentially pop up.
The best thing to do right now until this is resolved is to just watch your Paramount Plus subscription through your TiVo streaming device.
But if you want to continue using your Roku, like I said before, since you subscribe to Paramount Plus with Showtime (*unless you're linking to this from a provider account) you have a ton of options, so you don't have to continue to deal with this glitch since you have the choice of canceling Paramount Plus through the stand-alone channel app (or wherever you're currently subscribed to it) and subscribe to Paramount Plus elsewhere. You should check to make sure your show is on the other provider app before switching, but it should be there, and the price is the same.
I didn't include Hulu or Amazon Prime Video Channels in that list in my prior post since that requires a base subscription plan, and I know at least with Hulu you would still need to link your account to the Paramount Plus channel app to get all the content Paramount Plus has to offer since with Hulu it's just a Showtime add-on much like Max is just an HBO add-on. I'm unsure if you would run into the same glitch by switching accounts since this could potentially be account-related, but since this is happening to more than one subscriber then that's unlikely.
After a couple of months, you can then switch back to see if the issue is resolved if you don't like subscribing through the other provider. I tend not to like subscribing to any other than the main provider (unless I can link the provider I'm using to the main channel app like I'm currently doing with Hulu) since I've noticed that others appear to lack certain content such as various movies, but I don't know if that holds true with shows.
I'm uncertain if this option is still available, but there are promo codes online that allow you to have a month's free trial to the Paramount Plus channel app -- even for returning subscribers, so in this way, you can easily check to see if the issue is resolved without having to pay for two subscriptions once your billing cycle ends with the one with the faulty rewind issue. Just make certain to cancel the subscription before the month's free trial ends so you're not then being charged for two subscriptions. The promo codes only work for the Paramount Plus stand-alone channel app and not with the other providers.
*Of course, switching providers wouldn't be an option if you're subscribed to Paramount Plus with Showtime through a linked provider account such as through a cable, satellite, or TV streaming subscription. If you are doing this, you can see if "toggling" the account helps, but I doubt it will since I just changed over from using Paramount Plus directly to using Paramount Plus through Hulu and I still am not experiencing this glitch. But it may still work: Go into your Paramount Plus account from a computer or smart device and unlink the provider, log out, then go to paramountplus.com/partner, re-link to your provider, and log back in. If it is a channel update glitch then this probably won't work.
