Can no longer expand replies to Facebook comments

iOS and iPadOS

I am running the latest version of the Facebook app on my iPhone 6 and I am having a problem. Previously, if there was a comment underneath, say, a news article, for example, and that comment had received multiple replies, you could double tap the comment and choose "reply" from the menu that appears. This would take you to a screen showing all of the replies to that comment and you could also add your own reply at the bottom. Now when I try this, I just stay at the main view of everybody's comments. I cannot seem to get inside the expanded replies view anymore. Has anybody ran into this? Has anyone figured out how to do it?
