I remixed one of Google’s Firebase starter projects; it’s at important-chopper-1. When I open
firebase.json, click on Deploy to Firebase, and log into my Google Account, a Log Out of Firebase button appears and the Deploy to Firebase button shows a loading indicator.
At this time, according to the help video, a a list of my Firebase projects is supposed to appear. However, the loading indicator never stops, and the list of my Firebase projects never appears.
Refreshing the project page at this time seems to log me out of Firebase as if I had never clicked Deploy to Firebase.
