To make changes to a release, just make the modification (as long as it is allowed by the channels) and forward the release to the same originally selected channels.
To do this, you must enter the release, go to the "6. Distribution" tab, and select "Update on all channels".
Keep in mind that if you make changes to the album title or artist names, these should also be reflected on the cover. Changing the audio or the cover image will involve a new Quality Control review.
The process is the same as that of a distribution order, but in this case the system will automatically detect that it is an update. For this reason, the order type will show you the "U" for Update instead of the "D" for Distribution.
This operation has no additional cost if you have accepted the new pricing policy. And the timing for the Update to be applied in stores is 2 to 10 business days.
