I did notice that although does not seem a way to remove a show from "Continue Watching" in Freevee with a remote button, that I was able to just launch the show from the Continue Watching and then Fast Forward all the end. That seemed to remove it from my Continue Watching screen.
Not the most elegant way, but does seem to do the trick.
I do not remember seeing a WatchList in Freevee though. Regarding my WatchList in Amazon Prime Video, I believe I just log in to Prime Video and when I remove content there, it removes it from my Roku device. I recall a "Remove from Watchlist" option a few days ago when noticed the *button no longer worked on the device itself.
As for the Search results issue, you are correct there. Many times shows up as available in the Roku Search to only be unavailable when you go to Freevee. A few channels are guilty of this and not updating their availability. (not even sure if this is channels' faults or merely a sync issue between all the different servers involved in the Search feature updating.)
