Probuilder boolean not working + other issues

Hey, I’ve recently started with a new low poly game using Unity, and i thought i could use Probuilder to build levels for it, but when i try to use any of the boolean options i get this error message.
I don’t know what i should do and i have tried uninstalling and installing the package multiple times.

As a side note, i also have a problem with making new polygon shapes with Probuilder/Progrids, as i can’t put down vertexpoints.

The version of Probuilder im using is 4.0.3 and the version of Progrids im using is 2.5.0f0 (Unity Version 2018.3.6f1)

Hi! Yes, sorry the Boolean tool is very much Experimental (hence the label) currently.

Regarding setting Polyshape points there are some known bugs in-progress, however as a test/workaround, can you try ensuring the grid is “below” your view, then click on it to set points?
