When a probe has been paired with multiple app devices, the timing of when an app was launched on the device and when a probe begins searching (waiting to pair) mode can result in the selection of the wrong device when multiple users are attempting to work in proximity.
1. Close the app fully (do not just put it in the background)
2. Power off the probe
3. Move a minimum of 1.5 meters or more away from the other probes and display devices
4. Launch the app
5. After the app display shows "Searching for probe", power on the probe and hold it near the mobile device (around 10 centimeters) to ensure it will detect the correct app device as being the closest.
