Paramount+ app on Roku has a nasty bug when entering from a deep-link (Search, What-to-watch or an ad): it opens content with the Default profile.
It does not use the previous, last-used profile ("B") nor does it ask which profile to use - it always opens the links into the "master"/owner profile ("A").
It does not sound like a lot but is detrimental, consider a TV where profile B is used exclusively to watch. "B" Searching for a movie and jumping into P+ from there - it ends up polluting A's history/tastes profile - and gets registered for "continue watching" under the wrong profile
