We're implementing an app with subscription APIs. After I added SellingPlanPlanGroup like this page, I successfully added SellingPlanGroup and SellingPlan. However, GraphQL query to SellingPlanGroup returned empty object {} as billingPolicy and deliveryPolicy like following
[{"node":{"id":"gid:\/\/shopify\/SellingPlan\/13172836","name":"Delivered every week","description":null,"billingPolicy":{},"deliveryPolicy":{},"createdAt":"2021-01-18T04:04:14Z","position":1,"pricingPolicies":[{}],"options":["1 Week(s)"]}} ... ]
BillingPolicy/deliveryPolicy is always like {} and pricingPolicies is always like [{}].
How can I get billingPolicy/deliveryPolicy/pricingPolicies of existing Plan? Seems like only way to get SellingPlan is SellingPlanGroup.sellingPlans which returns like this.
