Reddit user Expert_Grape_9506 recently funded a U.S. Bank account with a Chase credit card. After doing so they reported the following message in app:
You recently used your credit card to transfer money or to fund an account(s). This is like withdrawing cash, which has a cash advance fee and APR.
It then linked to another page stating in the future this would be coded as a cash advance (page isn’t in the way back machine, so unsure when it was created). Keep in mind this is a single datapoint and we haven’t been able to verify this. Mostly posting in case anybody else can confirm.
