Stand activity showing blank bars, not grayed out, even when activity is happening
Has anyone had this problem, where sporadically the stand activity on an Apple Watch 5 shows a blank bar even though stand activity throughout that particular hour has occurred? This is different than a grayed bar that appears for a given hour when stand/move activity doesn't happen and you have an idle hour. I cannot find an explanation anywhere for this phenomenon.
Additionally, some hours I may get a reminder at 50 minutes past the top of the hour to move if I have been idle. Other hours where I have also been idle, I will not receive a notification. Why does this happen intermittently?
