Variant Title King: Color, SKU

Firstly, thank you for being so kind as to offer this for free, when other app makers try to charge subscription based fees for simple things like this. It's a breath of fresh air!

The app works as intended, but does not seem to work on mobile. I am using Debut, and the only customization I made is to have the product change when variant image is clicked, and also show variant products in collection.

Any idea how I can get this to work on mobile? Desktop is fine. Thanks!
