Subscription Support for Shopify Draft Orders

Subscriptions and advanced subscription management features are not currently available through Shopify's Draft Orders.

What's affected:

Adding subscription products to draft orders

Performing advanced subscription actions (e.g., splits) within draft orders

Why this happens:

This is a platform-level limitation imposed by Shopify, not a limitation of the subscription app. Shopify's Draft Orders API does not currently support the subscription functionality required for these features.

Workaround:

For now, subscriptions must be created through the standard checkout flow rather than via draft orders.
