Device_tracker.<mobile> lattitude "None" - but Zones OK

I’m tracking a OnePlus device from the Android companion app. It reports entering and leaving zones correctly and if I check its state in Developer Tools, it also gives me itc current lat/long.

However, I have created a Camera for each device that returns a Google map. I get the right image back except for this device. Lat and Long are both returning “None”. But it’s working fine for the above.

Any ideas/.
