FIXED: It was a VPN protocol issue. ORIGINAL MSG: The emulator companion is not loading this morning. I have tried reloading the screen, reinstalling the app etc. It scans the QR Code but the load bar doesn't appear and nothing happens. My android phone just updated its software but it's still not working. I recently started using a VPN. Can this effect it?
I would start with the VPN as a suspect.
Here's out Companion and Emulator FAQ, in case some one else encountered that.
