Business-level accounts are able to manually-verify their domain/website (KB0066259). I don’t see this option available for Pro accounts (KB0057580). Adding a TXT/CNAME record to our domain seems to be the only option for a Pro account. But, it is not an option for us, for security purposes.
Could you verify that there is no way to manually verify a domain for a Pro account? If it’s possible, could you forward the instruction on how to do so?
