Hello, i somehow managed to work that. Try this: log into your microsoft account on computer and make a new alias, make that your primary alias.Also in your microsoft account delete your connection with facebook. Then go to facebook on your computer, go to Apps and delete your connection with microsoft. Of course, delete your FB connection from your Lumia as well. I also tried restarting phone the. Then go again to your microsoft account on computer, change your primary alias to one, which was original, delete the new created. Then setup your connection to FB in your Lumia. Also i restarted phone again. Then it worked. I can't tell you, that is the right solution, or it just somehow started to work again, but you can try this. It is working for me since.
