I had the opposite experience with Uber just recently - my card expired, and I tried to enter the new card (same number, different verification code and different expiry) and the Uber site rejected it complaining that the card had expired. I tried mobile app, desktop website, couldn't find any way around it. The site wouldn't let me delete the old expired card either.
I found I actually had to track down a third credit card from someone else, add that, delete the old one, add the second one, and then delete the third one. For some startup I might expect that, but it's surprising to have to manage my billing this way for one of the most prominent apps on the planet.
I just checked the Android app, there was an option to edit the credit card (Payment, click card, top-right menu, edit. Delete is in same place). That seems to allow changing expiry date, CVV and country.
