Nope, not a problem for me.
Let me remind you that my comment was specific to foreign purchases during Apple Card in Apple Pay transactions.
I use a different card that provides extended warranty protection, recent purchase protection, return protection for domestic big ticket items (like appliances, tech hardware, etc.). If I buy a new computer, phone, dishwasher, I use this other card (let's call it Card A). If I buy a new phone, drop it, and smash it to smithereens in the parking lot of the Apple Store, Card A has my back. Apple Card would leave me hanging. That's why I use Card A for these types of purchases domestically.
I would not hesitate to use the Apple Card (for 2% Apple Pay rewards) during overseas travel for things like clothing purchases ($500 jacket, $200 shoes, $100 shirt, etc.), fancy restaurant meal, concert tickets. It's not like I need a warranty for these. I already drank that bottle of wine, I tried on that blazer in the dressing room.
