Hey!
I’m having issue with my homepage autoplay video, it autoplays fine in chrome browser, but it doesn’t play in safari. 
This is the code I’m currently using in custom liquid section.
Hello @GabijaZ
This is Amelia at PageFly - Shopify Advanced Page Builder app.
Could you please check if your iPhone is in Low Power Mode or if the battery is running low? AutoPlay will be disabled when the device is in these states.
Hoping my solution helps you solve your problem.
Best regards,
Amelia | PageFly
