App Store review 1.2.2: the app didn't register the chosen plan. App Pricing doesn't populate
currentAppInstallation.activeSubscriptions or send billing webhooks, so the plan now comes from the
Partner API activeSubscription query. Shops with no subscription (new install or reinstall) are sent
to Shopify's plan selection page; Partner API failures never redirect or downgrade.
