Your UPI mandate request status on the Dhan app doesn't update in real-time. However, it will soon reflect in your IPO order book. Typically, it may take up to 24 hours for the payment status to update once the mandate is approved. This information is received by the exchange. As long as the funds are blocked in your sponsor bank, your bid will be considered successfully submitted.

Note - If you cancel a bid and place a new one, make sure that the application no. of the new IPO matches the UPI mandate before accepting it. This ensures a smooth processing of your application.
