This app Logi Options+ has an issue.
After installing it, I have connected my logitech mx master 3 to my mac but the app keep telling me I have no connected device. After disconnecting my mouse I have tried to add it again but after successful pairing I still cannot se my mouse among my devices in this app.
So for me this is poorly designed app and I have to uninstall it. Not quite what I was expecting from the app for the 100e mouse..
