Trial app create experience is different depending on browser and authentication method

Using this link https://code.visualstudio.com/tryappservice/ in Chrome, authenticating with GitHub or captcha takes you here:

Authenticating with Microsoft takes you here:

Same behavior in Safari, except authenticating with Captcha takes you to https://code.visualstudio.com 😭

This happens when you try a different auth method after you already have one resource in the same browser session (different tab or same) . Likely because the browser sends the previously cached session information. There was some discussion around this earlier, cant find the issue. Created a new one to track this for future.

Workaround: use a different browser in this case or close al inPrivate sessions and open a new one
