Paramont+ subscription

I purchased Paramont+ thru Xfinity but cannot get all content such as 1923 and Landman without additional payment. It appears Paramont does not recognize the Xfinity paid app to view all content and according to some forum discussion is not a partner with Paramont as some providers are.

Why wasn’t there a disclaimer about limited content viewing before I paid the full amount of $119.99.

I haven’t found any place in the forum that this issue has been fixed. Please provide some amicable resolution.
