Hello everyone, I'm new to Evernote. I am using it on my iPhone and on my new MacBook Pro. So far this problem has occurred on both OS X Yosemite last week, and now it is continuing after I upgraded my OS to El Capitan. My only issue is that I am trying to select the feature in settings so Evernote Helper will start when I log into my computer under the General tab. I select the feature, and as soon as I close Preferences it reverts back to being unselected. I have restarted my computer, restarted Evernote, logged out, logged back in, and finally uninstalled Evernote and re-installed it. Is this a Premium feature or something? If not, any idea how I can get this to work? Thanks for your help.
