Tiktok not giving notifications for comments... on purpose?

For months now, there are certain times when I won't get notified that someone left a comment reply. A lot of the ones I've discovered are sometimes not the friendliest of comments. Is tiktok purposely hiding comments from us, I'm not understanding??

​

It just happened again today. I got a push notification on my phone of a comment. Went to the app, opened the notification area, and the comment notification was not there! I even changed the drop down to show comment notifications only and it was not there. I went back to the original post and the comment reply from the other person was still there. Why is this happening? Is anyone else dealing with this? It screams intentional by tiktok imo.
