Apparently if someone sends you a link to an unpublished story- you can go between all the unpublished episodes repeatedly until you read enough chapters to “unlock” the app? I have no idea if that works but try this:

Story is mine, unpublished and will never be published. You should be able to toggle between episodes on the right with the buttons and I think that still counts as a “read”?
