In a press release, Barnes & Noble announced that with the release of NOOK Software Version 6.1, users would no longer be able to buy directly from the Barnes & Noble NOOK App for Android, as well as the NOOK HD 10" Designed with Lenovo.

Members will now need to manage their membership through the Google Play Store App. RELATED: Apple Is Banning iPhone Users From Doing This, Effective Immediately.
