I noticed something strange this month. Normally expiring credits are used first. But I came into March with a ~$34 credit, without a visible expiration date, from a refunded Uber Eats order (driver marked it delivered but no showed, never called, etc). This month it has been using that balance first before drawing down the March Amex credits. I only mention it because it makes me wonder if Uber cash credits caused by Uber refunds are treated differently for the order that they get drawn down? Has anybody noticed something similar?
