I've installed the Gadgetbridge app on the Bangle.js and whilst the icon is shown in the status bar of the watches screen it's not listed under the available apps.
Tried uninstall & reinstalling, refreshing the device as instructed. Also restarting the phone, but no joy.
The Gadgetbridge app on the phone sees and can connect to the Bangle.js fine & the status bar icon indicates whether its connected or not but earlier versions had a few simple settings available.
Has the app changed such that it doesn't have a listing & settings?
