Clarification on ACM certificate renewal for a domain we no longer own — risk of charges or resource linkage

Hi, this is a follow-up to my previous question — “Does ACM certificate renewal failure affect data stored in AWS services like Glacier?”

We previously owned the domain umassmedgaolab.org, but we no longer own or manage it. However, we recently received an AWS ACM renewal notification for a certificate that was originally issued for that domain.

My questions are:

Since we no longer own or control the domain, could the new owner of umassmedgaolab.org use that certificate or in any way access or utilize our AWS resources?

Is there any risk of billing or charges to our AWS account because of this expired or renewing certificate?

Should we manually delete this ACM certificate to prevent any linkage or automated renewal attempts?

I just want to confirm that there’s no possibility of resource sharing, usage, or billing impact from a domain that we used to own but no longer do.

Thank you for clarifying this situation.
