I just installed full TeamViewer 12 on my computer and my Dad's. Not the Windows 10 app store version, which doesn't seem to work very well. I configured him for unattended operation, and I added him as a computer on my TeamViewer account. I was able to successfully initiate a remote control session, but while the remote control was going on, I couldn't figure out how to start a video call. Are they mutually exclusive?
I started a meeting, with myself as Presenter. I was able to see the video from my own camera in the separate window with a black border. When I clicked on Invite, I was able to see my Dad listed, but clicking on his item in the Contacts list didn't do anything.
So, what is the correct procedure for doing a remote control session and a video call to the same computer, at the same time?
