Revenue is gone
Hello, I am an author who uploaded some ebooks and made a little money. One day I tried to redraw them but I couldn't really figure it out how. A few weeks later, when I had time and after a I documented myself I acces my revenue section from my accound and any date I set it shows 0 usd..... I can't see how many pcs from each book was sold either. I live in Europe.
What happened? If you encountered this problem please tell me what do I need to do to fix it.
Thank you in advance
