TeamViewer on your night please make sure your TeamViewer is VERSION 13.2.
Make sure you are connected to the internet and TeamViewer is running. (Taskbar bottom right Windows, top left Linux)
I need to do groups at a time I keep everyone in a group for their night. I start at 10PM when someone's is turned on late I need to wait on all of them.
This is how I see everyone's computers black = off, blue on. Sometimes black is no teamviewer running, no internet.
