Update, this is an edge case on our end where you create a Zoom App on the Marketplace on a Personal Zoom Account, then your Zoom Account is added to a Master Account as a Sub Account. The Apps in the App Marketplace aren’t transferred over to the Master Account properly.
As a work around, create a new Zoom Marketplace App and it will be properly instantiated on the Master Account.
We are working on fixing this. JIRA: ZOOM-111363
