Account linking instructions

For those who are stuck on account linking, I've accidentally stumbled on a sequence of steps that might help.

Enable testing

1. In the Google Actions console, click on Test at the top menu, then click on Simulator on the left menu.
2. Click on Change version. A dialog box will come up. The dropdown says VERSION - Draft. Click on the blue Done button.
   A message will come up saying Test enabling..., followed by Test now enabled.

Note that step 2 above is crucial and not explicitly mentioned in the README. Without it, selecting your app from the Google Home app on your phone will do nothing, returning immediately to the "Manage accounts" page with the list of providers.

Account Linking

Now that testing is enabled, selecting your app from Google Home will open the built in browser which tries to navigate to the authorization URL. The browser will then close and go back to the "Manage accounts" page.

This next bit will sound really strange but it worked for me.

1. Select your test app again. When the browser opens, tap repeatedly on the area just below the URL, around the center of the screen.
2. If you got the right magic spot, the browser will pause, showing the URL oauth-redirect.googleusercontent.com, with a plain Return to app hyperlink.
3. Tap the Return to app link and account linking should succeed.

You will then see the devices created in the Setup sample service step in your Google Home app.

Tapping the magic spot works for me.

You are a life-safer! This MUST be in the README, as without it the steps are worthless and lead to frustration since Google Home app does not notify you that there's an issue, just fails silently :(
