Shopify Markets with Proxy full screen apps

[Qbrico]

We develop an app that creates app proxy pages but we take over the full screen/experience.

Its a proxy app where we host the landing pages we create even if the domain remains the same.

However i m struggling to understand how to allow merchants that use multi-currency / language and shopify markets to use the app.

we don’t have access to the Shopify object because we use full-screen and override the theme. Whatever we use would have to be available through the admin API.

What do you guys recommend?
