Your partner uses a newer version from Mac to PC
Just trying out the app for personal use, when attempting to connect to Control Remote Computer - get an error that says: "Your parnter uses a newer version of TeamViewer. Would you like to update TeamViewer now to establish a connection?"
Options are Cancel and Update.
Cancel kicks you out of the loop, Update says "Your're up-to-date! TeamViewer 14.7.1965 is currently the newest version available"
I'm from a Mac running Mojave 10.14.6 going to a PC running Win 10 Pro - just downloaded the installer yesterday.
