[AmplifyWaitTimeout] The domain association has failed because we did not find the CNAME verification record on the DNS entries of your domain

Hello.

You can check the CNAME record when you add the domain using the steps in the document below, so why not try adding it to Route53 yourself?
https://docs.aws.amazon.com/amplify/latest/userguide/to-add-a-custom-domain-managed-by-a-third-party-dns-provider.html

Just had this issue. Make sure your contact information for the domain is verified. AWS sends you an email that, for me, went to spam. https://us-east-1.console.aws.amazon.com/route53/domains/home?region=us-east-2#/DomainDetails/<your-domain.com>

Once i was verified it worked
