Cloudflare isn't going to wildcard every domain on their platform just to cure stale cache DNS issues.
replyThat wasn’t the ask though.
replyThe product is falsely advertised as is:
"Cloudflare Quick Tunnels"
This is on one (or two) particular domain(s) where setting up wildcard DNS should be relatively trivial, if they actually cared enough about the UX of this product to make a special case in their code.
I don't understand how people can launch stuff like this.
