Three tools on the same page each carried a quiet assumption that an account only ever has one domain. That was true when each was built, and not for a while now.
Added on purpose, useless on arrival
Consider an account with additional domains that exist only to redirect to the main one. They are added the way the page says to, and land in their own folder as promised. Then there was nowhere to tell them what to do next. The page that redirects a domain only knew about one domain, and the page that edits a domain’s DNS likewise. Both had been right when “the domain” and “the account’s only domain” were the same thing.
The tool that answered a question nobody was asking any more
Ask a single-domain tool to work for a second domain and it doesn’t error or warn. It keeps answering about the first one. Every field, save button and “successfully updated” message is real and works as designed, aimed at an address that wasn’t the one just chosen. That is a harder bug to trip over than an error message, because nothing about using it feels wrong.
Fixed by remembering there’s more than one
Both tools now take the domain as a real question: a selector where more than one answer exists, and a link that knows which domain it points at. The redirect control moved onto the page that already lists every domain by name.
A gap in folder control
Nothing let a domain’s folder be changed after creation. If two domains were to share content without one redirecting to the other, there was no way to say so. That is now possible for every domain except the account’s first, which stays fixed on purpose because too much else assumes it never moves.
