When a zoom app is set up, a developer email is required. It feels very unexpected that warnings for breaking changes, webhook validation errors etc get sent to the application owner, rather than the developer email.
Why this is problematic:
The “owner” is tied to a single zoom user account from what I can tell. Often apps are managed by a group of people for redundancy - eg if the single user is out of office, on leave, leaves the company, etc. We use and expect notifications to come in through the developer contact email - this also provides us a way for notifications from zoom to be received by a group of people rather than a single individual.
