Did Microsoft just fix WP8's Messaging app?

You'll know what I'm talking about if you've used it - not all messages people send you on FB make it to your phone. Yesterday, while I was working, I got a blast of over 100 messages that had not synced over correctly. Ever since, every message has made it to my phone (messages I send to other people are, sadly, still not synced). Can anybody else corroborate on this?
