I’m not a fan of Libby. I have used Overdrive for several years and while it is a little slow in maneuvering, I much prefer Overdrive over Libby. For example, I had accidentally deleted an audiobook from one device before I had had a chance to listen to it. I was listening to it on another device. The audiobook did not show up on the second device. I contacted support and was informed I only had to sync it. I informed support I was sure this was a programming issue but they disagreed. They said syncing should resolve my problem. Syncing did not work. Second, I like to listen to my audiobook before I fall asleep. Overdrive can be programmed to 15 minutes where Libby starts at 30 minutes. It’s easier to backtrack the audiobook at 15 minutes rather than 30 minutes. I’m continuing to use Overdrive for now.
