I have the new Teamviewer 13 on both Windows 10 (the remote host) and Linux Ubuntu 16.04 (the client).
The new Teamviewer's toolbar and features are restricted indeed. The clipboard doesn't copy between machines; I cannot find how to transfer files; there is no option to optimise for speed (the host has a slow internet connection); there is no remote update. EDIT: Also, there is no option to resize the remote computer to its original size on the client machine.
Is there a way to access the old features, or have they been deleted from Teamviewer 13?
