For Xbox players: Is there an update under My games & apps > Games > Ready to Install? Some players have also reported that several restarts/hard restarting their Xbox helped, which makes me think that an update needed to go through still.
For Uplay players, I'd recommend verifying files. I've seen a report or two of this working.
I'm unsure what the equivalent would be for PS4 players, but I would check your Downloads to see if anything is waiting to start up.
My guess is that the update still needs to go through for some of you: https://www.reddit.com/r/thedivision/comments/bclh98/all_safehouse_exits_have_doorsblocked/ektug74/ .
