I wish there was some kind of indication (like a tiny text in a corner) about if a song is in 320 kbps or lower. Not all songs are available in that rate, but it's still useful information for some people.
Well I can proudly say the update worked for me, and tracks are now sync'ed at Extreme Quality.
A point to note however, the quality setting was still on "Extreme" when I opened up Spotify, and I knew that my last sync was done with the bug (so was all low-quality) so I went into the options, selected "High Quality" where it told me my existing content was low quality and asked if I wanted to re-sync, so I said No. I then went into the options again, and selected "Extreme" and when asked to re-sync, said yes.
Off it went re-syncing my entire collection, which is something it never did before. So, you've made me happier.
I just hope that Spotify will learn from this and ensure that thorough testing takes place in future.
That's because we happen to use the same copy (text) for the 'resync' notification both when you switch from low quality to higher quality and also the other way around. Your tracks are still synced as extreme if that's the setting you used when syncing.
We have a ticket for this internally, but it wasn't fixed for version 0.4.24.
It doesn't really change my stance however. If I opt onto betas then yes I can say it doesn't work but iOS and app store isn't an open beta, so who is wrong? Spotify for not testing or apple for approving?
