What does Ping An Pratt & Whitney mean by forcibly closing the repayment channel?

Ping An Pratt & Whitney said that the forced closure of the repayment channel means the following points.

1 is the maintenance of bank repayment channels, and the repayment function will be temporarily turned off in third-party software to prevent abnormal repayment and losses to users.

2. The third-party software stops cooperating with the bank, thus closing the repayment channel. You can try again later or try to repay the loan the next day. If you still can't repay, then change the repayment method.
