This problem is present only in PC-ABS. On my M200 Plus with latest updates walls are not connected to the infill at all, I can put my fingernail between wall and infill. moreover, on walls with thickness of less then 2.x mm there is no infill whatsoever, only empty space. The problem is already visible in preview window of z-suite so, I suppose, z-suite is the root cause.
Stl, zcodex and report attached.
