I have been using the Indusind Bhim UPI app for the past couple of years. I had my UPI ID alias set and saved to my other payment apps as usual to receive money to this account. Today, when I was transferring money to my IndusInd account with the same UPI ID, it said the UPI ID was not valid, to which I tried with some different apps & got the same results. It seems they might have deleted my UPI ID without prior notice to the customer. Strange to see; maybe they are upgrading or changing the system.
