Why is the IPO allotment status not available on the RTA’s portal?

No Allotment: If the IPO was oversubscribed, shares are lottery-based, and you might not get any; non-allotted applications often don't show up.
Application Error: Issues with your PAN, Demat ID, UPI ID, or bank details can invalidate your application.
Payment/Funding Problem: A failed UPI mandate or insufficient funds results in rejection.
RTA Processing Delay: The registrar (RTA) might still be processing applications, or there's a technical delay on their portal.
