What I need to help my dad is the ability to initiate a connection from my Windows 10 PC to my dads Chromebook even if no one is logged into the Chromebook. Unfortunately this isn't the functionality I need. It appears I am unable to view the Chromebook screen unless someone is logged into the Chromebook. Sometimes it doesn't display the Chromebook screen until I click on the Host app on in the launcher bar on the Chromebook. When I choose a window and click on the 'Share' button, sometimes the screen sharing area in my Windows 10 Teamviewer app displays the screen from the Chromebook. On the Chromebook a 'Share your entire screen' window appears, prompting the Chromebook user to choose what they would like to share.
