I need to merge my trailhead accounts as I have a ton of progress on an older account and now Salesforce is starting to track my Trailhead progress internally. I don't see the point in having to retake the training just so the points/badges are associated with an account they report on. Please let me know how to accomplish this.

I'm experiencing a signficant delay when attempting to install the managed package to complete the Security Superbadge -- over 45 minutes and no email marking completion or evidence the component(s) have installed.  I think it's just an Apex class so flagging in case there's a systemic issue.
