Why is lighting (or reflections) different on mobile (Android & iOS) builds

In the Scene and Game windows, the beads in the game look just the way I want. This is the Game window view:

But in both the iOS and Android builds, the beads' reflections are undesired, here is how they look:

The reflections still seem to be there -though I am not sure- but they are VERY thin. I tried a few fixes but none of them helped me. Why is this happening, and what is the way to get around this? FYI, I am using Universal Render Pipeline (URP).
