I have been using Spotify v0.4.24.65.gaef36bd1 with a Late 2009 iPod touch 3rd gen 8GB (MC086KS, iOS 4.2.1).

But now it doesn't anymore sync the playlists like my newer iOS devices running a current version of Spotify and iOS 9/10 do.

Any changes I do to the playlists on my Mac (OS X 10.11.6) don't sync to the old iPod. I have logged out/in, rebooted, reinstalled Spotify, set Spotify offline/online, deleted/rebuilt OS X Spotify folder but the problem persists. The same problem is with a new LG Smart TV OLED55B6V: also its Spotify 1.1.5 for WebOS 3.0 doesn't sync playlists with other devices.

I can make a playlist with the old iPod and use that but I'd really like to sync the Mac's playlist as I did before.

Has there been a recent change that disables Spotify on old and new devices like that iPod and smart TV??
