Brand new MINI+ Z height wackyness

I have a brand new MINI+and can not get the z-height adjusted correctly.  While doing the calibration test I find that I can get the right side of the bed to stick (at a Z calib of -0.975) but the left side is about 5mm in the air!!!  How do I fix this?

I’ve taken a closer look and it appears the the Z axis is not quite perpendicular to the xy plane. Is there an assembly issue than can cause this? Or is this a known issue?

Kinda sounds like the X/Z arm isn't mounted perpendicular to the bed.

On the end of the X axis are the two idler screws.  Get 2 of something, anything, as long as they are the same length and will sit under the rods.  Put one on the right, and one on the left. Adjust idlers until level.  I used two metal rods the same length.  You can literally use anything.

Thanks!  I found the instructions for adjusting that at https://help.prusa3d.com/en/article/xz-axis-skew-correction-mini_158518   

However, even after adjusting those screws as far as they would go, the left side is still 2-3 mm in the air when the right is at zero.

After chatting with the extremely helpful prusa support, this is a know issue with a simple fix for some people.  You slightly loosen the two screws each on the front and back of the right base extrusion, rotate the whole z-axis until it is level and then tighten them down.  They will be adding that to the manual soon.
