I've done all things recommended to help with the playback failer issue. I can't listen to any of the books I have paid for. Not only have I paid for books bit I have 7 credits i have paid for and am scared to waste on something i cant use. I don't want to continue a membership with an app that doesn't work. This is an issue that others have also been reporting for months now. All I wanted was to be able to read during my busy life. I feel let down and honestly scammed out of my money.
