NX450H+ App digital Key
 

The digital key will not complete registration / will not work on my wife's iPhone 13 Max. It works on my iPhone 10 Max. Both phones running latest IOS Dealer first said it was an iphone problem, then said primary phone cannot have digital key. Tried deleting my account and removing app. Deleted accounts and app from car an phone. Dealer did factory reset on car. Nothing seems to work. Never tried my phone as the primary, but the dealer reversed their claim that the digital key doesn't work on primary phone. When digital key was working on my phone I tried sharing the key with my wife's phone, that didn't work either. Have not tried this with any other phones.
