Translations can only be viewed and edited for content or widgets in the Draft, Ready, or Production stages, and not for content in the Archived section.
Case 1: You archived content, but there is a version of that content in Draft, Ready, or Production.
Translations continue to be available for the content in Draft, Ready, or Production.
Case 2: Your Archived content is the only version on the Dashboard.
Translations are not available for this content, and it is removed from the list of content in your translations.
Info
When the Archived content is restored, the translations before archival are restored.
