Products that require a subscription for purchase, but have no selling plans associated with the product variants, are no longer available for purchase in the Online Store sales channel. Previously, a product would become available as a one-time purchase if no selling plans were attached.
The Liquid property
requires_selling_plan on Product and ProductVariants has been updated to reflect this change. The Liquid property still states whether a selling plan is required to purchase the product variant. Previously, the property would return
false if the product was set as subscription-only in the admin, but had no selling plans associated with the product variants.
