For in store pick up, the phone you want physically needs to be in stock and must show available for pick up in order to place the order. If the store is out if stock and unavailable then it’s usually grayed out.Apple does not seem to want my money.
I want to pick up (iPhone 15 Pro) in store rather than risk delivery problems. But the (Apple Store) app wont accept the order due to unavailability. I am happy to wait. Is this usual ? Advice welcome.
