Previous SAB apps would download the audio for the next chapter while the current chapter played. This provided a seamless audio play when finishing a chapter, the next chapter would appear and the audio continued playing (when SAB audio settings were set to advance to next chapter).
SAB v 12 no longer does this, instead the audio downloads at the beginning of each chapter resulting in a delay for the user.
It would be nice to see this audio buffering be part of SAB again to provide a better user experience. If it was added it would be good to have options to download more than 1 chapter ahead, so a user could more quickly have a whole NT downloaded. Also the app needs to know the next book/chapter 1 to download next when downloading is completed of the last chapter of the current book.
