Getting issue while setting event notification endpoint url for multiple sub domains

Description
Currently, we have set up a JWT app and also added a few event subscriptions for getting various event notifications for multiple subdomains. But, we are getting event notifications for some subdomains and not for others.

Now, we would like to know that is there any way to set a single event subscription for multiple/all subdomains related to the primary domain.? We have also tried setting up values based on this documentation OAuth with Zoom, but this didn’t help.

Error?
A few subdomains getting event notifications and some are not getting it.

Which App Type (OAuth / Chatbot / JWT / Webhook)?
JWT
