Why is my BHIM UPI not working?

BHIM UPI may not work due to technical issues like bank server downtime, poor internet connectivity, or an outdated app version. Other common reasons include entering an incorrect UPI PIN, exceeding daily transaction limits, or using an inactive bank account. To fix this, ensure you have a stable network, verify your account balance, and check if your mobile number is correctly linked. If the problem persists, try updating the app or contacting your bank's customer support for further assistance.
