I often receive the error: Visual Studio needs you to re-authenticate. Please go to Tools->Options->Azure Services Authentication, and re-authenticate the account you want to use.. It occurs first thing when I start the day, or about every 2-3 days. Often it occurs when I change branches (using an external Git Repo client), or changing locations (such as work vs home location). After re-authenticating, everything works great (for 2-3 days). Speaking to my co-workers on the same project, they never get it.
