I got my first Windows Phone (an 8X) a few days ago. I expected to be able to use the messenger app for facebook chat, but this is my experience so far:

Conversations are not synced with facebook, so in many cases I do not receive messages:

* I do not see messages that I send from my computer, or any device other than my phone.
* I do not see messages sent while my phone was off or otherwise disconnected
* Sometimes (not all the time) I do not see messages received while I was chatting with someone from a different device
* Even when I'm chatting with someone from my phone, incoming messages are often dropped. I never know if I've missed something. This is a serious issue, as I've responded to a series of messages that was missing an important dropped message.

These apps make the messenger app completely unusable for me as a facebook chat client. I can't imagine what type of user it *would* be usable for. Am I missing something here? Is there a way to make the Messenger app an acceptable facebook chat client?
