Preloader - Mobile Only? Also Ability to remove data-sets for Mobile only?

Does anyone know if there’s a way to have a pre-loader for mobile only on Wix Studio (not mobile app, just for normal mobile website breakpoint)?

I’ve stripped my mobile site down to the bare-minimum, used web speedy, used collection indexing, etc etc, and it’s still not fast enough (to our agency standards for google page insights), hence the need for a mobile only pre-loader.

Additionally, is there a way to remove a data sets (in terms of connecting to Collections from a page) for mobile breakpoint, only I’ve noticed if you remove a data connection for mobile, it removes it from ‘all’ breakpoints.

Any advice would be greatly appreciated.

Thanks

Stephen
