I use Apple Wallet functionality almost every week day, both via phone and watch. I did not know that the “bank card” in my Apple Wallet would expire independently of the physical card expiration.

It does. Looks like a two-year registration that must be redone, and isn’t a simple matter of updating an expiration date and CVS.

Apple Wallet then sent transactions to a credit card and put me over my limit. I did not note any notification anywhere the preferred bank card had expired. I’m wondering if I missed something, somehow. And I’m feeling disgruntled.

I only noticed at all because I went to check a balance and it was not what I expected. In the Wallet app on my iPhone, the entry for the bank card had a red expired indicator. But there was no indicator on the Wallet app icon itself. Thankfully, nothing had been declined and that was the worst of it.
