Feature: Feedback on the JS SDK Tutorial page (Auth0 JavaScript SDK Quickstarts: Add login to your JavaScript App)
Description: I’m going through the vanilla JS tutorial and have some feedback, plus, I’m stuck. 
Issue 1
First off, it wasn’t apparent to me that the right hand side changed as you scrolled. I was on part 3, as you can see in this screen shot:
And as you can see, in the right hand side it’s still showing info on step 2. I read step 3, had no idea what code I needed to add. I was about to give up when I accidentally scrolled down a bit more which triggered the updated:
Issue 2
On step 4, you are told, " Create a login button in your application that calls loginWithRedirect() when selected.", but you aren’t given any direction on how to do this. The implication is that you add a button and you write code for the handler, but the code in the previous step had the handler already, and wanted you to use a button with a specific ID. A reader can figure this out of course, but it really should be more clear. Why not simply show the required HTML (login button, logout, profile)
Issue 3
And at this point, I’m stuck. I was able to click login. I selected Google as my login provider, was that ok? When I get back, I get errors in the console:
From what I can tell, it dies here: await auth0.handleRedirectCallback();
So, was I wrong to login w/ Google? I did a second test where I made a new user, and get the same issue when I return.
