Before we submit your app to the Apple and Google Play stores, we need you to enable a mobile template for your Shopify store. Apple will require a mobile optimized site all the way through the app experience to approve the app.
You can do this without impacting the current template you have already selected (read more here). 

To enable mobile templates for your Shopify store, please do the following:
  1. Go here
  2. Click the "Get theme" button
  3. Click the "Publish as my shop's theme" button
  4. After it installs, click the "Go to your Theme Manager" button
  5. When you get there, you will see the "Simple" theme as your current theme. You will see the original them you selected as an "Unpublished theme". Click on "Publish" by your original theme to republish it.
  6. Now your original them will be published to the site and "Simple" will be unpublished.
  7. Click on "Publish" by the "Simple" theme.
  8. Click on "Publish as Mobile" to publish the "Simple" theme for mobile only.
Now you have a main site theme and a mobile theme. We will use the mobile theme in the app to make your shopping cart and product pages look mobile optimized.
