After weeks of having a WhatsApp Cloud API up and running, suddenly all my phone numbers can no longer send messages. Keep getting (#200) You do not have the necessary permissions required to send messages on behalf of this WhatsApp Business Account.

I have already checked the Meta Token Debugger, and my token has all necessary permissions (whatsapp_business_management and whatsapp_business_messaging (and business_management just in case)), and have added (and re-added) (system)users to my WhatsApp accounts w/ new tokens, but no luck.

I already have a support case with Meta, but so far they've been radio-silent, and it's kinda business critical to make sure my bots are able to reply to any request, so trying here too.

    I believe it's related to https://developers.facebook.com/docs/graph-api/overview/access-levels/ where for usage of "System user" auth token you need to request "Advanced Access" for your app within "App Review" -> "Permissions and Features"
