Amazon: Why is pre-order enabled in my release?

For any album or single sent to Amazon Music, the pre-order option will be enabled by the channel until the release date. The users will be able to see the cover image and listen up to 30 seconds of each song.

If this may be of your inconvenience, the delivery can be done to all the channels (except from Amazon) and, once the release has been published, updated and sent to Amazon channel.
