I've been experiencing problems with receiving Facebook messages within the integrated Facebook chat on my WP8 device from an iOS device running the Facebook Messenger application. I just don't get this messages whilst I can see them in the messages page on the Facebook site on my PC.
When the other person uses the Facebook website on their PC I am able to receive the messages and get them immediately.
Is there anybody else who has experienced this problems, too and got this to work in any way? Or is it a known problem with no workaround existing?
