I have confirmed that I'm at the correct OS version for Paramount Plus (9.4), and I have tried the channel on three different units ( #Roku Premiere (4620 series), #Roku Premiere+ (4630 series) and #Roku TV ) with the same results:
When I launch the channel, I'm presented with two options: Sign Up for Paramount Plus, and Sign Out.
When I click on "Sign Up ..." it says: Account Exists. Looks like you've already subscribed ..." Please sign on. This is correct, because I've had a subscriptions to CBS All Access for some time now
When I click on "Sign out" it logs me out, and then when I launch the channel again I'm presented with Sign Up (which I get the same message as above), or Sign In. When I log in, I'm again presented with the original two options: Sign Up or Sign Out
If I highlight the channel on the home screen, and then use * I don't have the option to delete/remove the channel, and if I choose Check for updates, it says the channel is already up to date. Same when I go to Settings|System|System update: it says all software is up to date.
I am having the same issue. I've tried everything I can find for help but nothing is fixing the problem. I've updated the app, verified supported OS levels, reset my router, deleted and reloaded the app, canceled and renewed my subscription. I still get the message sign up or sign out, even though I have subscription.
I have not contacted roku, but would will monitor here for a possible solution. My latest attempt was to unsubscibe, delete the paramount app, unplug and repower the TV, reload the app and renew my subscription. Still getting the same result.
@laurakg1979 and @Mark_63 - opened a ticket with Roku. First level support had me go through all the steps that @Mark_63 went through, with the same outcome: didn't fix it, so I've been "upgraded" . I'll let you know what comes of it.
