I was excited that UberEats was working for other folks, and was hoping it was going to be like the Airline credit that "can't be used for airfare" but gift cards usually work.
So, I finally signed up for an Uber account and added my PLT as my only payment. At Ubereats checkout, my payment "couldn't be validated". I did not try without the "credits" checked because I wasn't interested in paying the $5 delivery out of pocket for a restaurant 2 miles away.
