The explanation is as follows:

The best repayment amount refers to the credit card repayment amount that should be paid off in full on the due repayment date.

The optimal repayment of the day is: the bill amount of the previous period+the overdraft withdrawal transfer part between the billing date and the repayment date-the deposit part between the billing date and the repayment date.

If the optimal repayment amount of the credit card is 0, it means that there is no need to repay the current bill. After handling the credit card repayment, the information of the amount to be repaid will generally be updated the next day. For today's repayment, you can check it the next day, or check the credit card details to understand the posting situation.
