Hi, I have enabled the ambient movement of Image Banner on Dawn theme (9.0), it is working properly on Desktop but not mobile (iOS), I have tried different browsers on mobile but still not working. Is it not meant to be for mobile?

Hi,

The ambient still works on my iOS.

You may need to update your iOS.
