Light Cookies in iOS?

Do light cookies work in iOS?

I am using Unity 2017.1. Standard shader with one direction light with a light cookie. Everything renders normally in editor but the light cookie disapears on build to iOS with Metal. Any ideas why this might happen? I have been troubleshooting for a few hours and running out of ideas. Thank you for any insights on this.

I solved it. I turned the light cookie to ‘Important’ This fixed the problem. Hope this helps someone else.
