I have an iPhone 14 Pro.
I've carefully followed all these instructions, and Nightstand Mode continuous operation is still very hit and miss. The clock and local weather are displayed when I first rest the iPhone on the charger, at some point the weather will be substituted for my wife's first name and FIND-MY location, then later, the display will switch off. So in a consistently unpredictable basis in terms of timing and sequence.
I've tried several wireless and wired chargers, from Apple and Anker, updated the OS to the latest, turned Standby off and on. And the result is just the same.
I used to have a 3rd party app which worked rather well, but I was afraid of screen burn. Now I have the Apple OS equivalent which avoids screen burn by displaying random and unpredictable data then switches off the display!
Surely Apple is better than this? Frustrated is an understatement!
Thanks for any guidance you can provide.
