I updated skype to version 6 yesterday .  This morning i was invited to a group chat by a colleague using messenger.   I never got the invite but i was listed in the group chat on her box.  Worse, Skype 6 deleted Messenger from my box so there was no way for me to join the chat.  when i tried to join the chat on my phone, the phone client could not see the group chat either.  Is this a bug in the integration or do i need to enable something on my end?
