I came here looking for help with the same issue after waiting for a month with the book showing 'Approved' and being 'Active' for 16 days. I (wrongly, I guess) presumed that when it was finally in stores, the "not in xx stores" would change to being in xx stores, so I waited because it had passed the validation checks and showed approved. I figured it would show up once Apple did whatever they're doing with it, so I was patient and kept checking back. (Caveat: I'm a first-timer and didn't know any better, and there sure aren't helpful hints, let alone obvious big red flags when the 'metadata' is wrong.) Just today I finally clicked on the 'not in xx stores', only to find that every one shows there's a problem with the metadata. What the @#$%...why is it showing approved and active then.
...So, why can't Apples guru's at least give some indication of what's wrong with the metadata they think has problems? If anyone finds a specific example of what is wrong with the metadata, I'd like to know it.
(btw, self-righteous quips like MichiHenning's posts aren't helpful...even if you think you're above everyone else here.)
