Apple Watch Nightstand mode does not turn display off after 15 or 70 sec. Also battery not charging in that mode
Just got new Apple Watch Series 2.
First charge was normal, without any problem.
Nightstand mode also worked as described: screen active only for 15 or 70 seconds.
Second charge failed. Watch stays on charge 4 hours and nothing changed at all.
After few hours of investigation (including restart, reset, Hard reset to factory setting, restore from back up, set up as new, etc) found that the reason of such fail Nightstand mode.
It's not going off anymore.
Once I place on charger, it's activating screen and stays like that forever.
Try to charge from Mac USB, iPhone charger and iPad (12 W) charger, but nothing helped.
Only turn off and deactivate nightstand mode.
Any idea why the nightstand mode always keep screen on?
How I can get it back (for 15 or 70 sec only) if I did not change any settings between 1st and 2nd charging?
Apple Watch Series 2, iOS 10.2
