Not receive webhook event

Can’t receive any webhook event except the endpoint.url_validation event.
We have a private app and add all the events in the following event type Meeting/Recording/User/User Activity/Chat Channel/Chat Message. Originally it can always receive the webhook event. Since yesterday, I can’t receive any event. I tried to change the webhook URL and click the validate button. I can receive the validation request and pass the validation. But I can’t receive any other events like meeting created, chat message sent…etc.

I’m experiencing the same issue. Were you able to resolve this?
