Hi,
I've got my VA4 sleeping time set for 11PM-6AM but last few days when I go to bed at 10PM (or even earlier) and read book for an hour my watch count this time as a sleep (mostly light sleeping time). I think its connected with time when I lay down in bed. than the watch starts to count sleep.
Of course it can cbe edited later but didn't have this case earlier... Do you have similar problems? Is there any solution for that?
