Title says it all. I posted a book, it was there and now it is not but it is still available for sale and it is not blocked. Is this just a temporary glitch? It does show as having 500 page reads on KU which I have heard is a placeholder or perhaps a troll attack.
Usually if someone tries to check their Bookshelf and finds it blank, it's because they logged in with the wrong username and password. Log out and try logging in again, carefully typing the info rather than relying on auto-fill. (Did you try to change your password? Many end up accidentally creating a new account when doing so.)
But you say you can still see your Reports? This makes it odd. Log out, close your browser, and try again in case it's a glitch. And yes, sometimes you'll get 500 pages read as a placeholder until the bots catch up.
Yes, there does indeed seem to be a glitch, which has evidently affected many of us. (I seldom check, so I don't know if all mine are there. All I care about is that they're still selling, and November is looking pretty good so far.)
