Persistance = false not working for show
As far as I can tell, when I open a document in show with persistance = false in the request, I would expect after all the collaborators leave the document and close their browsers the document is removed from your servers. However I close all sessions (by closing all the Zoho tabs on my browser) and even after coming back hours later to open the same document using the documentId stored localy - the remoteStatus is returning true, and the user logs on as a collaborator without having to upload the document - which also has all the last edits on it still showing.
For security the document should be removed as soon as all sessions are closed as your API states.
