You haven’t seen some of my clients. They’re more than trainable. I took them into a store to use Apple Pay and they love it, once I shown them how to do it right. Others when the iPhone X asked them to double click the button she did the volume button. And Apple wonders why they see low usage.
Same with other “hidden” features like Airdrop! Or Continuity because for some reason some of this doesn’t set itself up. Or SMS Forwarding.
Case in point we need the home bar.
