Domain is caught by "threat intelligence feed"

The company I work at is in the process of migrating from a .app domain to a .com domain. However, one of our employees noticed that the .com domain (and all subdomains) are blocked by "threat intelligence feeds" on Windows. I've done a bit of digging and cannot find where this feed is defined or how to verify a domain that is currently blocked. Is there an official process for this? I'm happy to provided any information necessary in order to prove we now own the domain and it is not malicious. If there is an official process or contact at NextDNS to reach out to, please point me in that direction.
