Shopify 2.0 themes can be used on the Shopify Checkout Integration with the 2.0 subscription widget.

Stores using the Recharge Checkout on Shopify do not have support for Online Store 2.0 themes out of the box and will require additional code customizations to integrate Recharge with these themes. As per the Recharge Scope of Support, this type of customization is not supported. If you are not working with a developer currently, it is recommended to work with a third-party developer to implement a 2.0 theme. You may also consider converting to the Shopify Checkout Integration if you would like to use a Shopify 2.0 theme for the best experience long-term.
