Dynamics365 Guides (preview) sign-in issue
I had Guides (preview) working fine. I would sign in to the Guides app on my desktop and HoloLens with my Azure account and everything worked seamlessly.
Then, the next day I could not launch ANY apps on the HoloLens for some reason. I would just have the 2D panel of an app floating and nothing would happend. I couldn't find a solution to this so I did a factory reset. I reinstalled Guides app on the HoloLens and went to sign in but now when I select my account and try to sign in it immediately goes back to the sign in screen with no notifications or warning messages whatsoever.
I can sign in to my desktop version of the Guides app no problem.
Any idea what is going on? Does something on the device change when you do a factory reset?
