Laptop connection works fine with wireless or wired. But it says that Desktop connection requires duet-air which is a paid subscription. So, you can connect using laptop but can't connect using desktop unless you get the paid subscription even if you are on the same home network. Desktop connection doesn't work with wired, it has to be wireless which is paid. Don't see the point in paying for the app and then paying annual subscription to use the app with the tools it was designed for.
