why are a lot of the videos on my for you page getting cut short?

I don’t know if anyone else has this problem but a lot of the videos i get look like they should go for a lot longer, but then abruptly stop in the middle and restart. Like a video will end while someone is in the middle of a sentence.

Another example is i’ll see a video about their “top 10 favorite whatever” and it will just end halfway through number 8. And it’s not intentional cause the comments are talking about his top picks. It’s so weird and annoying.
