The next time I tried to use my Apple Card, it was declined.
Strange. I checked the Wallet app, and the balance was below the
limit. I remembered the Apple support representative mumbling
about Apple Card, so I did some digging through my email to see if
I could find a connection.
As it turns out, my bank account number changed in January,
causing Apple Card autopay to fail. Then the Apple Store made a
charge on the card. Less than fifteen days after that, my App
Store, iCloud, Apple Music, and Apple ID accounts had all been
disabled by Apple Card.
We all make bets on these ecosystems. Even if you host your own email at your own domain name (to name just one service) you’re probably not running the actual server. And even if you are running the actual server hosting your email, you’re still placing a bet on the service provider / data center hosting the server.
