Unlink Existing Availability Rules

To remove availability already linked to an entry you can use the unlink argument in an object’s availability input.

mutation updateEpisode {
  updateEpisode(uid: "ee884e98-f3e5-4929-b7ad-75b8fca1e64e", episode: {availability: {unlink: ["d53332c0-6ed6-4c97-996f-b5bc4982ba98"]}}) {
    uid
  }
}
