I hit Pay with UPI, but I haven’t received a notification. Now what?
Every collect request you receive will be visible inside your UPI app. In most cases, you will receive both an app notification and an SMS. So you can go to the transactions tab in your UPI app and the collect request should be there. You can then make the payment.
The collect request will be valid for 24 hours - i.e. you have 24 hours to pay via UPI once you hit Pay with UPI. After that, you will need to hit Pay with UPI again so that you get a new collect request.
