I have setup exactly as described in the quickstart and was not experiencing that.
Mine works like this:
- In a new incognito window navigate to
http://localhost:3000 - Click login
- login with existing username/password
- refresh the page
- I see nav bar with profile icon and dropdown
In addition, the trailing / issue was actually not from the quickstart, but just on my end. Are you seeing any errors in the console?
