Hi All, i have a intro video that i want displaying full bleed, with audio, autoplay and play on mobile. I have been speaking to support and they say 'This isnt possible on squarespace, you need custom code' i have no idea how to do this. currently i have added my video as a background video on my home page. This auto plays but no audio and it doesn't play on mobile. I have iphone 10 and fast internet. Please can someone help me, 99% of the website traffic will be mobile so i want the video to play. Thanks Adam

Please can you let me know how to do this. I really need some help! thanks
