Artifact Signing: Identity Validation Still in Progress — Over 20 Business Days Waiting

Problem description

I am asking about the status of a Trusted Signing identity validation request for my account, which has been in the 'In Progress' state for more than 20 business days since the original submission. Despite completing email verification and individual identity verification successfully, the status has not changed, and there have been no error messages or indications of pending actions.

Environment

Product: Trusted Signing - Preview; Subscription type: Developer; Resource region: West US 2; A Trusted Signing code signing account was referenced in the case record. No region, resource name, or resource group name was captured in the available materials.

What I've already tried

I have not tried anything yet.

Current status

I am seeking assistance to escalate this case to the identity validation team for a review of the current status and to determine if further action is needed, as the process has exceeded the expected processing window without resolution.
