FYI - found a USB Buxx workaround for how many new cards you can add as funding sources... My account has been stuck for 2.5 months saying I've hit the max allowed sources b/c you can only add 2 in 24 hours, 3 in 30 days, and 5 in 180 days.
Go to funding sources and EDIT the EXISTING funding source card. Worked for me. Still can't add new one's though.
Hope that helps some of you. On that note, anyone know how to find out when your re-set date is for adding new funding sources without calling?
