Issue with comments – Facebook Review

Every time I go to a post I’ve got a comment notification for, it loads the post, likes, and shares, but no comments will pop up, be it a personal post, posts in groups, etc. I have to keep going onto Facebook on my laptop to get comments to load at all. I have tried logging out and back in and uninstalling and reinstalling the app. Please fix this.
