I used uber the other night which is linked to PayPal as the default payment method. The two transactions, I found, withdrew money from my non-default bank account that is on file in my PayPal account. This caused my checking account to be charged $30 due to insufficient funds. Why would this happen when months ago I set my PayPal account to withdraw money from a completely different checking account when there isn't enough money in my PayPal account?
