Change to sales reports

To further protect our users’ privacy, transactions related to redownloads will be deprecated from summary and detailed sales reports for ebooks in July 2021.

The product type identifiers EB3 (free or paid book update), B9 (free or paid textbook update), and B10 (free or paid Multi-Touch book update) referenced in the iTunes Connect Sales and Trends Guide for Apple Books will no longer be captured in summary and detailed sales reports. All other values will remain in those reports.
