Your confirmation email states “You can manually approve the request immediately in the Overview page of the Cloudflare dashboard for your domain,” but there is no such manual approval mechanism there.
No one in the Community has the ability to make changes in your account. The email you shared indicates that a support request submitted from your Cloudflare account dashboard is the way to obtain additional assistance. With the transfer timeframe being five days, any support request you submit may not be addressed until the transfer has already completed, depending on how busy registrar support is.
That’s something you do yourself. When you open the domain in question (same place you went to unlock the domain), you should have the option to approve it immediately.
But note that even after this, some old-fashioned registrars can still take their godly time to show the domain in their dashboard.
A WHOIS lookup shows GoDaddy is already the registrar for the domain. So if it hasn’t appeared in your GoDaddy dashboard yet, you need to contact GoDaddy… as the domain should be in their possession now. (You can look up the domain on GoDaddy’s own site to confirm this: https://www.godaddy.com/whois)
Thanks… got it working after someone from Cloudflare responded. I had to use a different browser. That said, the instructions in their email are so vague that they are useless.
