The "New" Teamviewer is based on Device Groups, allowing you to free yourself from the owner and keep the groups in the event of its deletion.
There is a major problem in it, simple example.
I have 100 Device Groups and a new employee arrive. I need to modify ALL THE GROUPS to add the new employee in it one by one with the necessary rights.
Why we cannot simply create a user group (while the tab exists?) and just add this user group to all the Device Groups ?
At least, create a bulk edit to add a new user to all desired Device Groups.
We just can't use the new Device Group function just cause of that, it's really a shame.
Hope this functionnality will be added shortly.
