When autoplaying video appears in the main feed it is not possible to scroll using the area of the screen occupied by the video.
If the video is portrait, and fills the screen, it is no longer possible to navigate the feed without finding a way back or force quitting the app.
This bug was reported here previously and it was said at the time that it was iOS' fault and that the beta of iOS 17.1 fixed the problem. The problem remains.
