App Store: customer data requests, partner refunds, review guidelines

• Request customer data. On a customer's page, More actions → Request customer data downloads the data PlatformDTC holds on that customer, and asks every installed app that can read customer data to send you what it holds. Use it when a customer asks what personal data your store has about them.
• Tell a developer why you uninstall. Uninstalling an app now lets you pick a reason and leave a note for the developer. Both are optional.
• Deleting a customer now tells you that installed apps are asked to erase that customer's data (they always were).

New for developers

• Refunds. Refund a merchant's payment for your app, in full or in part, from your app's Earnings → Payments, or with POST /app_billing/partner/{partner_id}/charges/{charge_id}/refund. See Refunds.
• customers/data_request is now sent when a merchant requests a customer's data. See Compliance payloads.
• Uninstall reasons merchants give appear on your app's Installs tab.
• Review guidelines: everything a public app needs before you submit it, in one checklist.

Changed for developers

• A listing now needs a support email or support URL before it can be submitted.
• Submitting a version again after the review team asks for changes reopens the same review case, and submitting a version that is already in review is refused. Before, it could open a second case for the same version.
