It is driving me nuts. I have to clear stuff all the time. It's a like a new fulltime job. I can understand that Facebook messenger does not sync yet, but the MS apps? Like E-mail and Skype? Come on. When I have read something on my PC I would like it to disappear from my action center. I'm constantly clearing all the stuff that doesn't go away. Do guys think this will get fixed? I really hope so.
