Expectation: It's known it has different lighting interpolations method and quality for VLM on PCvsMobile; but Indirect lighting from VLM should provide similar lighting Direction on PC&Mobile.
Create an environment like the GIF image shows below(one ground, two static point light with different color, one movable sphere in middle)
Build lighting and look at the Indirect lighting provided by VLM
On PC preview, it looks correct that red from right and green from left; Switch to Mobile Preview the lighting direct is complete off, it looks like right 90 degrees off
The GIF shows how the middle movable sphere mesh look like while switch between SM5 and ES3.1
