I have a Mac that I have to leave on v 10.10 Yosemite and a Windows 10 machine. TV v13 always worked gret for me but now I keep gettting pop ups telling me I need to update the remote computer and that the session will time out after 5 mins - which it does. Not sure how I can keep using TV in any useful way. It seems all free accounts have to upgrade but paid accounts do not. Is that the case? Will be a real workflow killer for me if it is. Please let me know.
