Hello! I am working on an integration for leads with the ads I run on facebook and my CRM. For this I followed the steps on setting up an endpoint and configuring the webhooks product on the meta developer pages.
I managed to get a leadgen from the webhooks testing tool using the specific leadgen testing tool from the app's dashboard. I also checked and verified that my page-access token has the required rights to access and retrieve leads.
I however run into a problem trying to simulate the full lead ads testing tool (https://developers.facebook.com/tools/lead-ads-testing/) for simulating the entire process of making a lead and retrieving its data. My problem is that when I create a lead, the status of the test-lead stays on 'pending', and the Error Message displays 'Updated lead is still being processed and will be delivered shortly'. It seems as if the request is stuck.
I also verified that my app is indeed subscribed to the leadgen field using https://developers.facebook.com/docs/marketing-api/guides/lead-ads/quickstart/webhooks-integration/
I am using ngrok for tunneling the requests to my local environment, but that should not matter since I do receive the leadgen tests from the leadgen-specific testing tool.
Does anyone have any fix or idea what could be wrong?

In whatsapp cloud api Dashboard, under test number I get a message like this "Messaging may be unavailable. Review issue". , but it is still sending messages when i click the send message button, but my web hook has stopped working, it was working earlier

When I click to sign the "message_echoes" field, the following message is displayed "You could not subscribe to some of the fields requested due to a permissions error"
Can someone help me with this, I need to receive all the messages, including the ones I send to whatsapp myself.
