That sounds like a bug to me. You should be able to fully on board, from start to finish, in the client app. Just like you can do with Amethyst or Primal. The requirement that users go to the metadata.nostr.com site to input some profile metadata before the user can go to YakiHonne and complete the process is unacceptable as far as I'm concerned. The process you've come up with is a functional workaround, but this is something YakiHonne needs to address immediately.
