Why does my Facebook App indicate beta program for this app is currently full?

[Android Central Question]

I cannot 'like' Friend's posts, but I can leave comments on their posts.

The beta program is to test out a new version of the app. Once they have enough people testing it, the beta program is "full".

Which has nothing to do with being able to leave comments but not being able to like. (And if you're running the beta version, report it - that's what beta testing is for - finding problems like that.)
