Is this app compatible with all Shopify themes?

This app is only compatible with Online Store 2.0 themes.

It uses Shopify’s App Block and App Embed technologies, which are not supported in legacy (non-2.0) themes.

To check if your theme is supported, go to Online Store → Themes → Customize and see if “App Embeds” and “Add Block” options are available.

If your theme is not compatible, you may need to upgrade or switch themes.
