Why is the Allow Notifications and Allow Nearby Devices required to use the Libre app?
The Nearby Device permission allows an app to find, connect to and determine the relative position of nearby devices using Bluetooth. This permission is important to always have turned ON for the Libre app* to ensure the app maintains connection to the sensor and does not go into Signal Loss.
Allow Notifications:
If you wish to receive alarms† on your Android device, the Notifications permission must be set to Allow.
