Embed video showing on desktop but not mobile

Dear all,
I’m trying to embed .mp4 instead of utilising .gif so that load speed will be much faster,
but I am facing the issue that the video is showing on desktop but none on mobile.
I’m utilising external server as cloudinary.com

this is the code I’ve used:

Anyone can explain why this issue?
Thanks

Hi Andrea! i totally understand what you are facing right now,

Can you just kindly reduce the size of the video on the mobile view customization.

Hi! do you think that’s the solution? what should it be then the code?

Try changing to “max_width size:80px;” and lets see what happens..

my Develepor can actually do this without compromise..

? Nothing its happening, except the mp4 to be so small that you can barely see it….

Yes I’m happy to solve this issue asap thanks

Hi, you can add custom liquid code to your page:

Feel free to change the width if you’d like it to be something other than 100%
