Why am I unable to set my UPI PIN

Sometimes, when you try to set your UPI PIN on one app, it might not work. This can happen for different reasons. A good trick is to try setting your PIN through another trusted banking app that you use. Once you set it there, the original app should be able to find and use that PIN automatically. It's like teaching your card a secret code in one place, and then all the other places magically know it too!
