I saw a pop up in hdfc netbanking app which said "check your new limit on your card"(something like that). When I clicked on it and entered mobile, last 4 digits of card number and otp, it said "request could not be processed. please try again later". I didn't see that pop up again. I haven't received mail/sms for the LE. I really don't know what that was. Is it a glitch?
