Automated Webhook Check Failing On HMAC Verification For Mandatory Webhooks failed

I believe I have configured my mandatory webhooks correctly. But the automated webhook HMAC signature verification which is done when submitting an app for the store listing review keeps failing for me. I have verified that the webhook works as expected in two ways: 1- When I install my app in a test store, and uninstall it, after around 2 days I get a call to my webhook for data removal, as expected. It is processed normally and returns a 200 as documented. 2- If I call the webhook e.g. using cURL with an invalid payload containing a wrong signature, I get a 401 as expected. 3- I can see my webserver logs for both cases. However, when running the automated shopify verification, I can't see any logs. It simply fails after a 5-15mins with no specific error or anything. So I can't really troubleshoot what's going on, as it doesn't seem that Shopify is actually calling my webhooks with any data. How exactly is this verification being done then?

Same issue here, we need help from shopify people, documentation is really unclear and we have no logs to know what's wrong.
I also configured the mandatory webhooks with hmac verification but it's not working.
Did anyone find a solution please ?
