Sorry for your issues, but thanks for sharing them. You saved me and likely others ton of headache.
I was going to do the same thing, since it took me 5 different "reset password" cycles until I got the email address actually used for unraid. However I felt "Nah, I've already had to jump through so many hoops already, I'll save that for another day".
I'll save changing the email address for after someone says they were able to complete the process without issue.
