It's happening more and more now :( I'm commenting someone and they're not getting it as it's not going through. I check P2P and sure enough, no comments.
What's going on? :(

If the comment isn't going through, make sure you're on their profile to comment them. It's only a roundabout "fix," but it seems to work for me.
I'll try it, but not always does everyone have the comments box on their profile so that makes it difficult :S That doesn't mean I won't try it :)

If they're on your friendslist, try using the link under Personal > Friends. If they're not, try using the option to comment via their posts, if you can find one.
