Hi Aby!
Thanks so much for responding! This is a major issue with alot of templates I think! It's a shame also because the only way around it is to use custom css which Squarespace don't offer support with and can break the functionality of your site (which is why I generally avoid it!)
I couldn't get this code to work for me 😞 Probably because I haven't added my own info to it properly. Can you clarify what this code has done for you? Have you got it to show an image instead of video full time on mobile?? Would be great to chat directly - drop me a line on eleanora@ruralmedia.co.uk if you have time and we can try and resolve it!
Thanks again,
Elle
