Device OnePlus 6, Lenovo tab4 8 plus
Operating System Android 9 & 8
Besides of listening to music I also do enjoy listening to audio books on Spotify like the one below.
The audio book has 535 tracks, each around 2 minutes. Seeking between tracks will take from 30 seconds per track (OnePlus device) to a couple of minutes (Lenovo tablet device). Even pausing and resuming has a significant delay. Displaying the whole audiobook is 3 minutes at least and only the first 500 tracks are displayed. When I want to resume at track #515 for example seeking from the last selectable track (#500) to track #515 is a job of half an hour. I am pretty sure that this is neither a device problem not a bandwidth problem because it persists on all of my Android devices and the album itself is already completely downloaded for offline use.
This bug is really annoying.
