IAP Product Info Error & Sandbox Webhook/Test API Failures

Hello,

I'm suddenly encountering errors with In-App Purchases (IAP) and my sandbox webhooks, which were working correctly just a few days ago.

Specifically:

Product Information Error: I'm receiving the following error when trying to fetch product information: { "type": "product_info", "result": "error", "error": "An unknown error occurred" } This API call was functioning normally until today.

Sandbox Webhook Failure: I have configured a sandbox webhook, but my server is not receiving any notifications from the App Store.

Test API 401: When I attempt to call the test API (https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/test), I consistently receive a 401 (Unauthorized) error.

Could you please provide some guidance on how to troubleshoot these issues?

Thank you.
