iOS custom email error

I registered a domain through iOS and mistakenly added a custom email to my iCloud address instead of my wife’s (her first name), so I deleted it. Now my wife is unable to register that name through her own iCloud account. She just gets a “Something went wrong. Try again later” error message.

If you are trying to register the domain on her account, this will not be possible since the domain is already registered.

If the issue is with the email, you’ll likely need to reach out to iCloud’s support. Cloudflare is your registrar, iCloud is you email provider. This sounds like it is an issue with your email provider.
