We have a prismic repository with a few documents, one of them has the uid "." (dot) which represents the homepage in our implementation.
Somehow the uid of that document changed to "1" and if we tried to change back the uid to "." it won't allow us, showing this message: "This value is already used by another page_component document".
Exploring the forum we reached this topic: When does cache expire? (UID History) - Prismic for Content Creators - Prismic People
So we archived and deleted the document that has previously the "." uid, however, it won't allow us to create a new document with that uid even though now there is any document using that uid.
The prismic UI doesn't show any document with that id in any tab (work, planned, archived) but the API stills return the information and the UI doesn't allow us to create a new document with the uid.
