Everything in my Apple Wallet just completely disappeared!

The monthly automatic payment for my Apple Card happened as scheduled on 9/30 and everything was in my Apple Wallet (credit card info and statements, tickets, boarding passes, etc.) on 10/1. Then today, on 10/2 everything is just gone. There are two icons where I can start adding cards and items to the Wallet but my Apple Card information and everything else is just gone. What happened?
