About a month ago I submitted a support ticket for problems with Spotify on my Samsung Galaxy S III running Android 4.1.2. The worst issue was the constant buffering and stop/starting during playback. I have nothing but praise to the premium support staff. Over a period of 10+ days they helped me troubleshoot in every possible way. Their persistance paid off. After several tests and re-installations, I was able to play my playlists without hassles.
(1) Must a user go through the clear cache and re-installation every single month?
(2) I clearly must not understand what a "downloaded" playlist means. Why is there a waiting period between tracks? If the tracks are on the phone (or are they not?), then why the long, long delays in between tracks?
