Why the device is not responding to location queries, when the app is not in the active state (visible in screen)?
The background execution rights of the device is needed for the service. See instructions below:
Android:
Huawei phones are preventing background tasks by default. Allow it by modifying Settings -> Protected Apps (or Launch Apps).
Battery saving mode usually prevents the location discovery of the target device.
iOS: Use cases preventing location updates:
Missing authorization for "Always" location service (via Settings App)
Power saving mode
App version older than 1.6.13
WP: If you are using the battery saver functionality, allow background execution rights to the Team Locator app.
