Under a new policy all Meeting SDK apps are required to go through app review to access meetings outside of the developer account used to create it. Your app can choose to be on the app marketplace for discovery and distribution. If this is not required, then you can choose to have your app be unlisted.

Apps that require additional review have received an email with details from our app review team. If you have any questions, please go to the developer forum  thread. Please submit your application for review at least a month before your deadline to ensure a timely resolution.
