Near end of show, screen gets small, then switches to next episode
Near the end of a show, the screen associated with that show suddenly gets small (i.e., goes to picture-in-picture mode), while the rest of the screen is devoted to an ad for the next episode, or if there is none, to another show. If closed captions are on, it doesn't display then. Then - sometimes while the current episode is still playing, it switches to the next episode, or to the other show.
If I hit the OK button on the remote fast enough (on a Roku Express, and on a Roku Ultra 2019), it goes back to the original show, to the end. But in the mean time, if I have turned on closed captions, I miss a few captions. I've tried hitting the instant replay button to get them again - but it just goes back to the picture-in-picture mode and drops them again.
I understand this is a deliberate feature - that near the end of a show or movie, all you usually see are the credits, though you often also see previews, that I like to see. Also, sometimes a song with words plays at the end - and I want to hear it to the end. Also, on channels like ABC and Hulu, it often does this during the show, because the credits time is often shorter.
Is there a way to turn off this "feature"? I think there should be. I want to be able to see the show to the end, without the interference of this feature, before it does the auto-switch. If I do want to switch, I could always just fast forward to the end.
