Suggested fix: Add a phone number in Shopify admin under Store details (the settings area for the store’s contact information), then retry purchasing the subscription.

If unresolved: Account-specific investigation is required. The merchant should log in to the Shopify Help Center and start a live chat so Support can securely access the account and diagnose the issue.

Extras: The responder invited the merchant to share more about their products and marketing plans and offered getting-started resources.

Status: No confirmation of resolution in-thread. Next steps are to update Store details with a phone number and, if the error persists, contact live Support via the Help Center.

Hey, @appdesk .

Thanks for reaching out and bringing this to our attention.

You can add your phone number under the Store details settings within the Shopify admin. Once that’s done, you can try purchasing the subscription again. However, if you’re still experiencing an issue with purchasing a store plan after adding the phone number, then it looks like we’ll need to access your account in order to identify the problem. While we’re unable to provide account-specific support via the Shopify Community, we’d be happy to assist you through live chats. Simply visit the Shopify Help Center and login to your account to create a support request.

That being said, since you’re a new merchant on Shopify, then I’d love to hear more about your business and share some resources to help you get started. What types of products are you selling? Do you have a marketing plan prepared for your store?
