What should I do if my DTV application is still pending approval while others received theirs?

I submitted my DTV under Workcation on 30th April and still “Pending Approval”. As of now, the status still shows “Pending Approval.” Meanwhile, my friends, who applied on the same date, already received their Visa approvals on May 10th. I am beginning to wonder if there might be an issue or delay specific to my application that I may have overlooked. I would greatly appreciate any insights from others who may have experienced a similar situation, or any advice on what steps I could take next.
