Issue: Currently my org is awaiting Identity validation verification for our Azure Trusted Signing setup. We submitted a request last week and another request earlier this week. We're curious if there's anything that we need to do on our end in order to advance the current "In Progress" status (we have already verified the email) or if there's anything in particular blocking the status from progressing further. Let me know where to send any necessary details. Appreciate the assistance.
Resolution: Our org now has our identity validation requests completed so looks like our issue is resolved.
If you have any other questions or are still running into more issues, please let me know. Thank you again for your time and patience throughout this issue.
