I've been testing the product for a few hours and like the features but a very important one does not work.
Ctrl Alt Del (CAD) does not work with Remote Utilities agent to unlock Windows. I tried using the Windows Viewer and the Android app.
CAD does work with TeamViewer's QS agent so it should work without having to install any host software on the remote.
I did search the forums for a solution but it looks like this has been an issue for quite sometime and it was supposed to have been fixed already. I found a post where someone recommended using the on-screen accessibility keyboard but CAD only works when sitting in front of the remote and using its mouse.
