Does Shopify Advanced support selling_plan property in cart liquid?

[XINU]

Hi!

We set up a Subscription App for our Shopify store for only auto charging purpose. However, after testing, orders are not being placed with the auto charging plan subscription.

They suggest adding the selling_plan property in the cart. Does Shopify Advanced support the new Shopify Subscription API's selling_plan properties or only Shopify Plus?

Any guidance would be appreciated.
