Hi there!
Adam here from Shopify.
Were you speaking of this website of yours: www.svukshoes.com ?
I went on that website and viewed different products and the product options/variants displayed correct for me. I would click on the option, and a drop down area would show up which I could select the variant I wanted.
I am using an Android mind you.
What browser were you using on your Iphone to view the products?
Thanks, and hope you do find someone to get this fixed for you asap!
Talk soon :)
Adam
