Location not working on lock screen
I just switched from a Pixel phone to iPhone 13 Pro Max. One app I use is called Hubitat, a home automation platform. The app accesses phone location all the time, and determines when I'm inside or outside of a home geolocation. Years ago on my iPhone 5s this was pretty reliable, then on my Pixel 2 it worked well too. But now when my new iPhone is in my pocket that app doesn't know where I am. As soon as I open the phone and unlock it, Hubitat knows whether I'm home or not. What settings are limiting my location when the phone is asleep?
Note: Hubitat already has location access "all the time".
