In that period, did you maybe clear the existing cards' bill or something? No matter how many times I tap "Try Again", it is erroring out at the limit transfer page with "Something went wrong" error. Not allowing me to clear bill either as previous month's bill fully paid. This new BBPS system is horrible, doesn't allow unbilled outstanding dues to be paid until next bill generated (in case of crappy banks like HDFC, Yes Bank, Canara, PNB etc). Other banks at least least us clear the unbilled dues. This is HDFC crappiness at its absolute worst.
