Why is my UPI not working after 24 hours?

Your UPI may not be working after 24 hours because you entered your UPI PIN incorrectly three times. This action triggers a 24-hour block on transactions for security reasons, according to NPCI guidelines. If the 24 hours have passed and it is still not working, check your internet connection, confirm your bank account is active, verify transaction limits, and ensure your app is updated. You can also contact your bank or call DigiSaathi for assistance.
