I agree here. My MX Master 3 doesn't allow the use of the thumb scroll or the back/forward buttons. Which sucks.
To clarify. I am using MacOS, Catalina 15. VMWare Fusion version 11.0.2. The VM is running Windows 10 64 bit.
metoo posts make sense when you reply to an existing post that talks about the same problem and if that post is very active.
Please create a new post and do not forget to list your edited vmx-file.

First, Fusion 11 isn't supported on Catalina. You need Fusion 11.5 at a minimum. Try upgrading to a supported version, update VMWare tools and see if that fixes it.
