Ask HN: Cloudflare 1.1.1.1 doesn't honor DNS ttl?

I have tried 1.1.1.1 recently since it shows up pretty good in benchmark. I have a domain with DNS in namecheap and 5 mins TTl. I change the DNS and it isn't propagating. I thouhg namecheap DNS is bad but out of curisitory I do dig @8.8.8.8 my-domain and it resolves to right ip!!! Does anyone experience that? Or is it just me?
