Oh, this was the best. Guess all good things must come to an end. The backup funding source linked to your PayPal Business Debit Mastercard® will not be supported.Beginning March 11, 2019, a linked bank account will be the only backup funding source supported for your PayPal Business Debit Card. Any other currently linked backup funding source will automatically be unlinked from your PayPal Business Debit Card, including the PayPal Extras Mastercard, PayPal Smart Connect account, PayPal Cashback Mastercard, and eBay Mastercard.PayPal encourages cardholders to link a bank account so purchases can be made even when funds are not available in your PayPal balance.
