I am currently testing my web app in a local environment, and I have successfully implemented the WhatsApp embedded signup functionality. However, I am encountering an issue with receiving messages in the webhook after subscribing to it.
Here is a summary of the steps I've taken:
Implemented embedded signup successfully.
Obtained a code for generating an access_token using the "https://graph.facebook.com/v18.0/oauth/access_token" API.
Debugged the token and retrieved the waba_id using the "https://graph.facebook.com/v18.0/debug_token" API.
Obtained the phoneNumberId using the "https://graph.facebook.com/v18.0/:whatsapp-business-account-id/phone_numbers" API.
Registered the phone number using the "https://graph.facebook.com/v18.0/:phone_number_id/register" API.
After successfully subscribing to the webhook using the "https://graph.facebook.com/v18.0/:WABA_ID/subscribed_apps" API and receiving a positive response, I am not receiving any messages or data in the webhook when sending a message to the registered number.
If there are any additional steps or configurations needed to ensure the proper functioning of the webhook, please provide guidance.
Thank You.

As off today we receive a lot of "An unknown error has occured" when trying to publish. Do other have this same issue?

We've recently received a notice that our privacy policy link is invalid. We checkd app dashboard and curl response and everthing is fine. We don't know what is wrong.
The link is this: https://cdn.progeomedical.com/MyNutriverso/privacy-policy.pdf
Can you help us, please?

I'm experiencing a privacy policy violation. The URL works fine, but even if I resubmit, the submission is rejected as invalid URL. https://www.happypointcard.com/page/customer/term.spc?no=2 If you try to submit a support ticket for this phenomenon, you will receive a submission error. How do I fix this?

The Insights Graph API is missing data for several demographic data points, including page_impressions_by_age_gender_unique and page_impressions_by_locale_unique for many of our pages. This problem continues to grow each month to new pages, even though there are daily posts with strong audience engagement/reactions so there should be demographic data available.
For example, in the Graph API explorer, you can see we had nearly a full month of data returned back in July for this page: https://developers.facebook.com/tools/explorer/572800817920405/?method=GET&path=103060282112412%2Finsights%2Fpage_impressions_by_age_gender_unique%3Fperiod%3Dday%26until%3D1690761600%26since%3D1688169600&version=v16.0
but when you run the same query for the same page for this past month, almost no data is returned: https://developers.facebook.com/tools/explorer/572800817920405/?method=GET&path=103060282112412%2Finsights%2Fpage_impressions_by_age_gender_unique%3Fperiod%3Dday%26until%3D1705968000%26since%3D1703289600&version=v16.0
If you could provide some insights into why more and more demographic data for these pages seems to be missing with each month, when the pages have active posting and audience engagement, we'd appreciate being able to get to the root of this.
Thank you!
