Hmm. I have Facebook chat enabled, but I'm offline. And my incoming messages aren't showing up. I don't use Facebook CHAT at all, on the desktop or phone, but I'd like to send and receive MESSAGES. I wonder if that's a problem?
You mean offline messages right?
You can send messages to your Fb contacts while you appear offline on your phone - they will receive it.
However, like FB messenger on Android and iOS, integrated FB Chat won't let you receive messages from your contacts who also are appearing offline. If you however, appear offline and a contact tries to initiate a convo, you again won't receive it even though the other person is online.
For what you are trying to achieve these are the stuff you could try: (Note it is NOT what you want, I know it so don't shoot the messenger)
- IM+ (free ad supported) or IM+ Pro (paid version) can let you have facebook chat like the FB Messenger on the other two platforms.
- You can pin official FB Messages tile but it has horrible notifications and you'll have to keep refreshing it to see if you have anything in there.
- Pin FB mobile site's inbox - no notification but quicker chat access.
- Email notifications turned on - ask FB to send you an email notification every time you get a new message and then have your email sync "as item arrives"
