Snapping is working only partially

Hi

The snapping is working only partially like grid mode but not in vertex mode. To shwe the problem I have just 2 basic cubes close to each other but these do not snap as seen in the screen shot.

I’m using MAC Book (Catlina) and Blender 2.8.6. and 2.9.0.

I have tried all combinations in the Snap menu to get the cubes snap together. Few times those have snapped, but very randomly and only on top of each other and side to side (but just one side).

I really do hope that some could help me with this.
How can I get the snapping to work reliably?

–Timo!
