2022 NX450H+ Digital Key Issues
 

The digital key authorization step locks up on my wife's iPhone 13 max. It says something like Registering device with some waiting symbol. Waited a long time, never finishes and it does work / the digital key features do not appear. It works fine on my iPhone 10 Max. Both running the latest IOS. The dealer has attempted to get this working but hasn't succeeded. Anyone have similar issues? Any solution? We have tried many different things, uninstalling app, deleting account, changing registration order, etc.
