I've noticed something weird with sleep tracking. Not sure if it's a bug but it seems odd.
I generally don't have an issue with the times it logs for falling asleep and waking up. It's pretty accurate within 10 mins or so and I'm happy to edit it. That's fine.
What's odd is that I get given break downs of deep sleep, REM and light sleep etc. They change throughout the day?!
For example, I woke up, the app said I had 44mins of deep sleep (which seems low compared to Huawei Watch GT that I've been wearing for the last 9months) then say by mid morning I'd check my app again and that had changed to 37mins, then when I swiped down to refresh the app, it changed again to 35mins.
There's no need for this to change. I either got 44mins deep sleep or I didn't. Why is it adjusting every time I refresh the app?
