Artifact Signing Public identity validation failed without a reason

My Azure Artifact Signing Public identity validation changed from In Progress to Validation Fail.

The notification email only states “Validation Fail.” The Azure portal shows no failure reason, corrective action, or document request. The Azure Activity Log shows that the Artifact Signing account was created successfully and contains no failed validation operation.

I am a registered Swedish sole proprietor. My legal registered name is “Abbas, Majed,” while “Arabic Taskeel” is the product/trading name. I completed the identity verification and provided Swedish business-registration and domain-ownership documents.

Could an Artifact Signing support engineer check the internal vetting result and tell me what must be corrected before resubmitting? I can provide the subscription ID and identity validation ID privately to a Microsoft employee.
