When I first started using it, I was able to tag friends in comments and status updates just by starting to type their NAME. Then I had to use the @ symbol before the name. Now it won't tag friends at ALL (besides in pics) in any posts, status updates, or comments! This is VERY frustrating, & I have been searching for an answer for 4 & 1/2 hours! I just want to tag friends' names in my comments or posts. I have uninstalled and reinstalled several times and no help.
