Client OS, both ends: macOS Catalina 10.15.6
TV version, both ends: TeamViewer 15.7.6 (paid)
Issue: Actions -> Send key combinations is ticked but greyed out. Sending of key combinations, such as COMMAND + TAB, for application switching, brings up local application switching, not remote application switching and COMMAND + SPACEBAR brings up Spotlight Search locally not remotely.
Other points:
Some Finder key combinations do seem to work such as COMMAND + H and cut, copy and paste.
Behaviour appears to be the same whether in windowed of full screen.
Any suggestions before I open an actual support case?
