I am using TeamViewer 15. The User Manual I have is for TeamViewer 12. Apparently there is no manual for any version beyond 12.
Some (all?) of the instructions in the TeamViewer12 manual are wrong for TeamViewer15, for instance some of the directions for File Transfer. I've been able to figure out how to use that feature and others on my own, but I can't help wondering whether the TeamViewer support people want everyone to depend on the much less convenient online guides and have no intention of issuing any updated manuals.
Just a thought, no need to reply.
