What is wrong with this app? It used to work so well, now I can't even change my UPI pin. Everytime I try , it says sever failed, try again later. Please fix this ASAP. Edit : From 4 hours to 24 hours, I've waited for an email, and I have recieved nothing. Dear developers, I beg you, please. I truly regret making Paytm as my first choice for online payments. Nor I can change my UPI, nor I am able to make payments. Fix this, please.
