We had previously verified our domain under the wrong Apple account. I removed it from that account, and am now attempting to verify it under the correct account.
On this page: https://developer.apple.com/account/resources/services/configure
I've added the domain to our correct developer account, clicked "Download", uploaded it to the correct location on our server (overwriting the old file), and now I always get this error when clicking verify: "Requested domain name has been verified previously"
I presume this error is because I had previously verified this domain under the other account, but now that I've removed it, I would think that would have been sufficient to allow it to be registered correctly. Has anyone seen this before?
