DNS Error
One of my domains is having connection problems via IPv6. When I do the tests via whatsmydns.net, it finds an AAAA record, but in my Cloudflare account, there is no AAAA record registered in the DNS zones. I checked with other domains that I have active with Cloudflare and none of them have an active AAAA zone. I would like to know how to solve this.

Has anyone had a similar problem? Do you know how to solve it? Thanks.

When I do the tests via whatsmydns.net, it finds an AAAA record, but in my Cloudflare account, there is no AAAA record registered in the DNS zones.You have a proxied record. Proxied records do A + AAAA (IPv4/IPv6) automatically. I'd guess the ones in your other domains either are unproxied?
I think I understand what you said and actually when consulting other domains they all have AAAA records set automatically because they have the proxy (orange cloud) activated. My problem is actually that many IPv6 networks simply cannot load this site, they always result in DNS timeout like this print here from my cell phone via mobile data and I can't understand why if everything is fine with Cloudflare and DNS records.
The IPv6/AAAA records are likely unrelated. Browsers use something called Happy Eyeballs which tries both IPv4/IPv6 and will resolve both A/AAAA records, try them at the same time, and use whichever one returns faster: https://en.wikipedia.org/wiki/Happy_Eyeballs, so having broken/partial IPv6 wouldn't cause that, IPv4 would still work.
That error could instead be DNS Cache if you've recently added the DNS Record/changed nameservers. It could be blocking by them or an ISP. Or it could be some other configuration on their end. That error isn't a DNS Timeout but that their local DNS Server said it can't find anything to connect to, IPv4 or IPv6.
