For some reason when I am in a phone call on my iPhone 8 I can no longer transfer calls to other apple devices like I used to be able to. You know in a call there is an audio button and when I click on that button I used to be able to transfer calls to my Mac, Apple Watch, or iPad. I can still transfer calls to the iPad if it is on, but no longer to the Mac or Apple Watch. Anyone know how to fix this?
