I lost my American Express credit card. What is the fastest way to block it through the app or customer care to prevent misuse?

I've been a customer for 6 years. The biggest upside is the customer service. The biggest downside is the slow mobile app. If you do most banking on the app, test the app at a branch before applying — it's surprisingly old.
