We often play books and MYO using the app while out and about. It's really frustrating that the player will carry on playing from where you left off, but the app does not. It would be great if the app could remember where you got to on each card. Currently you have to find the track you were listening to and then scrub through to where you were (if we can remember where we were!). Other players such as Google Play Books remembers where you got to with audio books, this missing feature is really off putting!
Just to be clear, I do not expect the player and app to be in sync, but if you've played something in the app, next time you come to play the same card in the app, it knows where you stopped playing it last time you played it in the app
