Audiobook occasionally stuck loading

[KingThomas01]

I've only run into this a few times and don't know if it's a bug or a limitation that can't be bypassed. Sometimes when I open the app to start my audiobooks, it won't play, the controls will show as if it's loading/buffering even when the audiobook is downloaded to the device. You have to close and restart the app for it to fix itself. Edit: it also happened later when I was connected to a Bluetooth device, except this time, the audio was playing, but the controls weren't able to be used
