The app does not recognize that it has already been allowed in the Mac OS settings to start upon logging in- I have added both Logi Options+ and LogiPluginService into the list of apps to start upon logging in. I have also allowed Logi Options+.app and Logitech Inc. to run on the background. However I don't know, whether the Logitech Inc. item isn't linked only to the Logi Options (non plus) app, which I had peviously installed but uninstalled using the uninstaller. Sometimes when I log in into my user account on macbook after turning it on, the Logi Options+ starts as usual but then it asks me to grant it the start upon logging in permission in Mac OS Settings.
