Count me in on this issue. Last night at 11:20pm is the last accurate data point (and I went to bed later than that, so didn't die overnight).
A few data points from my experience
- I installed the "Human" app which syncs to healthkit. That's when I noticed that health app hadn't registered any data today.
- I removed the Human app, just to be sure
- I then noticed the Health app was getting ANCIENT data. Like, it recording some steps from 1981. I was old enough to be walking in 1981, but I'm pretty sure that even Apple's new fancy M8 processor is quite that good. (I have screenshots showing this data if anyone wants to see) I hadn't seen that particular issue referenced here yet.
What I've tried:
- I deleted the weird data points to see if that helped kickstart things again.
- I quit and relaunched the Health app
- I hard-restarted the phone
- I reinstalled the "Human" app, noticed that it wasn't registering any steps either
- I followed Apple's instructions that have been linked to from here. No avail.
Finally, I did a "Reset All Settings", which seems to have sprung it back to life. I now have data starting from about 2 hours ago. Oddly, all the data between 11:20pm last night and 4:15pm today seems to be completely missing. Given that the M8 processor is supposed to store about 2 weeks of data, this data loss is suspicious.
I'll report back over the next few days with any more updates. I'm going to avoid doing a full restore for now, and keep an eye on it. I've lost enough hours on Apple's bugs for one day.
