That hasn't been the case for me. I get ApplePay notifications for every POS charge for my Amex Platinum even if it's not via ApplePay. But I have cards from Chase, Citi, and Bank of America in ApplePay as well, and I only get notifications if it's an ApplePay transaction. I wish they all did it the way Amex does.

Edit: Actually, I mis-remembered. Internet charges on the Amex do cause a notification. But not for any of the other cards.

You need to enable this with credit card providers. I had to confirm a mobile number with Chase then set it up with >$0 auth.

I have cards from Chase, Citi and Barclay. Every charge yields a notification just like the AMEX.

Internet charges on my American Express shoot me a notification as well.
