Gone features?

I undownloaded TikTok for a few days to take a break, but now when I came back 3 days later I see a lot of features had suddenly disappeared. These include:

-not being able to watch a video at 2x speed by holding in the corner

-not being able to zoom in on a video i was currently watching

-not being able to repost by holding the like button

-not being able to quick comment emojis by holding the comment button

-I also felt the resolution had taken a downgrade

(Sorry if some wording is weird, subreddit kept blocking random words, so I could post the post.)
