Large number of books posting for zero revenue (over 70 books in a week)
Since around 10 March 2015, I have had a lot of zero transactions post - this happens periodically, and I understand that transactions that post zero revenue are ostensibly a purchased book being moved to another device, etc.
In the past this has been perhaps a few books, once it seemed like quite a few (close to 20 within a few days), but I thought perhaps there was some late ledger posting issue or whatever.
Well, in the past week I have had 76 transactions post for zero revenue; this is hundreds of dollars of sales for me, and it seems off. Anyone else experience this? I searched the forums and KB and didn't see anything about close to 100 posting in a week.
