I have recently uninstalled the lousy FB app and stopped logging in to FB via the browser in hope that my Lumia's FB integration will handle all my FB traffic for me via the People and Me tiles.It turns out that it's simply too good to be true. I have the following problem: back in the days of using the FB app or in case of logging in via IE, I used to be able to send FB messages to more than one recipient. The internal WP messaging system does not have that option anymore for FB chat and it is limited to one recipient per thread. Worse still... if I am included in a thread of messages sent to me along with other recipients, the messaging system simply won't deliver any of those messages to me. This is a serious shortcoming as it means I'm simply missing out on some of the FB messages addressed to me (as well as others). I really hope that this issue can be addressed in the next system update as I really don't want to go back to that below-par FB app for WP. I'm pretty sure this is a case of Microsoft just overlooking something here, but if I'm wrong & there is a different reason for this situation, please feel free to correct me.
