I suggest this is due (in part, if not entirely) to how you handled the DNS changeover from AWS to Netlify. You would have done well to read [Support Guide] How do I migrate a domain to Netlify DNS with zero downtime? before proceeding.
I am a community member. I do not have power to escalate issues. I have pinged two of Netlify’s engineers in a previous post. If you are on a paid plan that includes support you can try submitting a support ticket. You might also this compilation of support guides for troubleshooting DNS issues. Otherwise you will need to wait. There is no guaranteed response time in the forum as far as I know.
