Once the sharing has been received, it must be activated. To do this, just be within 5 meters of the SOLO, press the open button on the app and follow the instructions shown.
If the activation process fails, your phone may not be able to find the SOLO.
To solve the problem you need to make sure that Bluetooth and GPS tracking are turned on. These settings are required with some phone models due to a system bug, which prevents the phone from detecting nearby Bluetooth devices.
The "1Control" app does not track the position of your phone, it only needs to be active for Bluetooth detection of the SOLO, so it is also necessary if you are in an underground garage.
Once this step has been verified, if the device is not yet detected, it is necessary to verify that the app has all active permissions.
To set the app permissions, you need to access the phone Settings, select the "Applications" (or "Apps") sub-section, select the "1Control" app and enable all the required permissions.
