Hi, I am not seeing messages sent to me from contacts in UK and Canada but getting from US and other places. I can individual chat with the people but in my Groups that the same people are in I am not seeing their messages. in the Members list says "Unreachable" They see my messages in the Group though. I have tried deleting them and re-inviting them, I have upgraded my OS to same as theirs.????? Any Advice???????
