What to do if your sensor has plenty of time left, but suddenly disconnects.
If your BG line suddenly stops, but you think you have plenty of life left in the Libre sensor (and your transmitter is charged) a simple fix may be what you need.
Navigate to your devices menu in your Limbo app, click on the Libre sensor icon and click on 'x' to disconnect.
To reconnect, now click on 'activate' and touch your phone to the sensor. Most times this will fix the temporary disconnection issue and your BG line will appear.
