Topaz Studio 2 + Microsoft Surface Studio pen not working

I’m using Topaz Studio 2 (version 2.0.9) on a Microsoft Surface Studio 2. When I create a mask for an effect layer and choose the brush, the pen doesn’t work at all. Everything works just fine in Topaz Studio 1.

I think I saw some comment about Wacom tablets not yet working. Is this related?

Ift may be related, if there is a Windows Ink setting for the MS Pen turn that off and see if that helps. But that means there will be no pressure settings used.
