Even on a development store created with a Partner account, you need to subscribe to a pricing plan to use the app's features. On development stores, Shopify's specifications let you subscribe with a test subscription (free).
Cost: You can subscribe to either the Light plan or the Full plan for free (test subscription).
Features: You can use the features of the plan you subscribed to without restriction.
Subscribe: Subscribe to the plan you want to use from "Pricing" in the app admin.
For details about development stores, see Development stores | Shopify Help Center.
When you publish a development store, or transfer it (transfer ownership), the test subscription is automatically canceled. To continue using the app on a published or transferred store, subscribe to a pricing plan again.
A Shopify Plus store's development environment (Staging and Sandbox) is not eligible for a test subscription. It is treated differently from a development store created in a Partner account. We issue a dedicated URL that lets the development environment subscribe for free. Contact us by following the steps below.
(1) Install the app in both the production and development environments
Install RuffRuff Order Limits in both the production environment and the development environment of your Plus store.
(2) Request a dedicated URL
Request a dedicated URL through the contact form, and include the following information.
Store domain of the production environment (in the format XXXXX.myshopify.com)
Store domain of the development environment (in the format XXXXX.myshopify.com)
Name of the plan you want to subscribe to (Light plan or Full plan)
Tip: Installing the app in the production environment confirms that the development environment belongs to a real production environment. This prevents misuse disguised as a development environment.
