Ok, so I know that Facebook and Windows do not get along (does anyone but me get on with MS these days? It's lonely in here...). The result is that chat falls over regularly and one has to sign out (go 'offline') and in again to wake it up. This has worked since I got my 820 in Feb. Over the last week, however, FB has died completely and this method doesn't work any more. I have tried deleting the permission link in MS account settings and then removing FB from my phone, then switching off and then back on and reconnecting. Same problem, 'cannot connect to chat' constantly. No way out. I know my MS account is working with FB as my Win8 MS chat app works fine with it. Also, calendars and the like still sync. It's just chat. This indicates to me that it's something wrong with the FB side of things as there's no reason why MS would use a different method to connect to chat on each device. That would be looney. So, what options should I tweak on my MS account to at least get back to where I was? Help me Boffins, please!
