BUG [ANDROID] : Spotify desynchronizes everything once a week...

[Arcegis]

Friendly greetings !

I am currently running Spotify Premium on Android 4.2.2, on a Wiko Stairway.

I'd like to share you my discontent after something recurring happens :

Spotify desynchronizes everything I synchronized once in a while (for example, after an update is available, but I cannot update because a bug in the Play Store prevents me from doing so...It even happened as I was reading a song in the suburb train, not later than this afternoon !), and, sometimes, it won't let me synchronize some albums at all (for example, "Imaginaerum (Tour Edition)" from Nightwish will desynchronize each and every time I try to download it !)

It happened several times, and, so far, at every update. I am quite fed up to be forced to re-download 6 Gigabytes of music at every (failed) update (even though it only takes me a couple of minutes with my Gigabit Optic Fiber at home...).

Is there a solution to this problem, which DOESN'T include "Update the Client" (since, as I was mentioning it earlier, Google programmed their Store with their feet, and it won't let me update my packages even though I have the necessary place in my phone's memory...) ?
