Video feed scroll down

The Facebook app on my iPhone X no longer loads new videos under the video I have selected to watch. When a video is selected on my news feed, normally I can watch that video and scroll down to watch related videos. However for some reason, the application does not load more videos under the video, instead I can only watch that one video and swipe back to my news feed to scroll down for more.
Why can I no longer scroll down while watching a video to view more related videos?

Regards,

Update!!!!!!!!!!!! about Facebook, v163.0
