Is there a way to transfer the funds in Apple Cash to Apple Pay?
You can pay with Apple Pay using the funds in Apple Cash, so I use it for, ironically, Apple Gift cards using the Target.com app that accepts Apple Pay.
[edit: if you’re earning Apple Cash from your Apple Card, you could apply the Apple Cash toward your balance when you make a payment. I do the gift card thing so I can move the earned funds (including rewards from other cards) into my Apple ID account for “rainy day” stuff. I’m weird and even track all that in my accounting app. 😂]
