Can't access some of my Trailhead instances since newest update
Since the latest update to "link" your various instances, I can't access some of my past instances because I can't even remember what the username was. It used to appear in the drop-down, but now doesn't and I need that specific sandbox because of the Security Dev requirement and I don't want to retake those challenges. Can anyone help?
Please reach trailhead@salesforce.com. If you can remember your email id associated with those accounts, they will be able to find your accounts and let you know the username and can generate new passwords.
Hope this helps you!
If this helps you please mark it as solved.
Thanks and Regards
