If you have set a release to Final and it has been approved for distribution to the stores, you will not be able to edit the catalog number on that release. Instead, we would need to:
- Issue a takedown on the release (you can request this by contacting our support team).
- You can then duplicate the original release using the 'Copy' tool in the icon menu, set the new catalog number, and then set the new version of the release to Final.
Once this has been completed, the new version of your release with the updated catalog number will be distributed to the stores. It should be noted that you will not be able to reuse any previously distributed catalog numbers on any other releases.
