I pre-ordered an e-book back in October. I got an email saying it's available, but the app refuses to acknowledge I own it. I tried all 7 of the troubleshooting options, and I'm starting to feel like maybe B&N simply stole my money. If it's relevant, I use a Galaxy A11, and from what I'm seeing in the other reviews this is an ongoing problem. I would give this broken app zero stars if I could.
