USING YOUR APP AND FREESTYLE LIBRE READER WITH THE SAME SENSOR If you would like to use both the FreeStyle Libre Reader and the App with the same Sensor, you need to start the Sensor with the Reader first and then scan with your phone. Note that FreeStyle LibreLink and Readers do not share data with each other. For complete information on a device, scan your Sensor every 8 hours with that device; otherwise, your reports will not include all your data. This is NOT true. I followed these directions and after I scanned with my meter, I tried to scan with my phone and got the message "Sensor already in use - the sensor you just scanned was started by another device and cannot be used." I have a Pixel 3 and there is NO help when I search the internet - very frustrating!!
