Hmm. this is clear as mud to me.... So my courtesy default subdomain is bici.opalstack.com Where do i need to add the A record. On my opalstack CP? some registrar? What would an A record look like. May i suggest this be added to the documentation on the free subdomain that comes with our account? "Free opalstacked.com Subdomains"
I may have figured it out. I added an A record with this: 18.104.22.168... will see what happens
