Disabling copy and paste of text and files

Hi all,

We would like to stop our users from being able to copy and paste text and files to customers PCs.

I have created a test policy which has the following.

Even though I have disabled the ability to do file transfer and I have disabled clipboard synchronisation, it still allows me to copy and paste files and text...

Why is this...

See below images to show the policy has applied correctly to my client.

If someone could please advise, is it something I am doing wrong or is it's a bug with TeamViewer, as it has been driving me insane trying to get this to work.

Thank you!
