Amazon Pay balance can't be used for transactions in combination with other payment methods

Check screenshots below. They say we can't use Amazon pay balance for an order with other payment methods. This is some bullshit. I was redeeming my office points to Amazon pay balance. And I can't use it now for a big purchase like One Plus Pad 2. Because the wallet amount is lesser than the order amount. They want me to add money to wallet if I want to use it.

This is absolutely evil. Until last year we could pay with both Amazon pay balance and credit cards.
