After using the trydiscord domain and then configuring the real custom domain to use, 2fa breaks. I believe fido2 associates domains with the key.

Also another admin can’t disable the key, it becomes “invalid parameters” (same as [Can't turn off 2 factor](https://meta.discourse.org/t/cant-turn-off-2-factor/155513)). Trying to migrate again to the same custom domain will also be denied because “Hostname already exists.”.

My account is then bricked, please advice
