I'm using the official Facebook app. Sometimes as I'm going through my newsfeed, it'll say, "Insert person's name here commented on this. Two-finger double tap to interact with this story." If I two-finger double tap, I usually get choices like Hide, Hide All from this User, Mark as Spam, and Cancel. I never get to find out what the item is actually referring to. What, exactly, did that user comment on? What's causing this?
