How Long DNS propagation takes?

DNS propagation takes
0 – 72 hours to be updated
So if your verification doesn’t work immediately
after you updated ”DNS records” then wait for 2 – 72 hours
then you try the verification again.

Note that in some cases, DNS propagation can takes up to 2 hours, 3 hours, 4 hours, even 24 hours or 72 hours to propagate worldwide  successfully.
