Thank you.

I tried it but it is still shown in horizontal.
I am using Debut theme, which is 5-6 years ago. I wonder if there is problem on this theme.

Because my friend also send a link to me which it works in horizontal in his Shopify website. However, it is still shown in horizontal on my website.
