Hello,

1. I have enabled the “Separate cache files for mobile devices” option in the settings of the WP Rocket and it seems that everything works correctly, so show the video how it doesn’t work for you.

2. I checked on the default theme that issue and I see that there is the same issue, here is a screenshot: https://monosnap.com/file/EqiTWfihoDwhcqHNEJyYeGxerBYXa4 . So seems that the issue related to WooCommerce itself.

Kind Regards
