For content types like web content, translations follow the same approval workflow as the original content. For content types that don’t have approval, translations cannot be reviewed either.
Furthermore, it is common to want to review the translation to a set of content together and be able to approve and publish them all at once.
The translation approval workflow will solve these needs. Translations will be kept separate from the final content and can be grouped in a set of translations for approval. Once approved, they will be applied to all content at once.
