About 4.7.2 mobile preview

The distortion effect(refraction node in material) actually WORKS VERY WELL in editor es2 preview and mobile preview,but it does not work on mobile(iphone 6 plus),I know that the refraction is not implemented on mobile yet,but why does it work in mobile preview?
I hope this effect will soon be available on mobile since that is very useful in particles.Thanks!

Here’s a screenshot of distortion in es2 preview:

Hello ,

Thank you for your post,
I have been looking into your issue and unfortunately this feature is not expected to run on es2. This feature will hopefully be implemented in es3.

Thank you for your patience,

Thanks,but it indeed can be rendered in es2 editor preview…Hope this feature be implemented soon for metal just like gpu particles…
