I got many emails from Atlassian re: Domain not confirmed (DNS records).
In fact the domain in question (ADAYTON.COM) domain did show as validated "domain"
BUT on the "ADD email" setup page I could not ADD emails (RED X) so I did follow the instructions to check and ADD the four DNS records to the domain registry host and initiated the "CONFIRM DNS) button.
Subsequently ALL four DS requirements lines switched from NOT confirmed to GREEN check mark (VALIDATED).
That was a week ago but I still can not ADD domain emails to that account domain?????
HELP!! :-)
