Online Store 2.0 App Embeds
Shopify's Online Store 2.0 (OS 2.0) themes support App Embeds.
App embeds are the default way to enable app components in a theme.
Discount Ninja provides two App Embed options.
[RECOMMENDED] Stable release: enable the stable release (and disable the latest release) to use the latest stable release of the app.
Latest release: enable the latest release (and disable the stable release) to get early access to new features and recent fixes.
IMPORTANT: enable only one of those two options on each theme.
