Need to log in on every reboot, offline lists gone

[ttex]

Hi!

I have a big problem with Spotify on my Nexus 7 (2013), everytime i reboot the tablet, i need to log in again in Spotify and all offline lists needs to be redownloaded.

I have searched far and wide and tried everything, and it has basically made Spotify unusable.

I have tried:

*Reinstalling the app (many times)

*Factory resetted the tablet

*Flashed Cyanogen Mod

*Cleared offline devices in account management

*removed/connected USB OTG flash drive

Nothing works, still the same. It's been like this since summer and last update (made in December on my tabled) does not solve the issue.

I was wondering if it had to do with starting the tabled (and Spotify for first time since reboot) without internet connection, but it seems that it does not really have any effect.

The actual files is still there (Spotify taking 9GB) but no playlists are offline. I think it is the relogging itself that causes this, and not Spotify not finding the files

What do I do? I'm loosing my mind here

Device: Nexus 7 (2013)

Android: 6.0 MM Stock (Root)/CM13 (Root)

Spotify version: Lates (As of early December 2016)

No external storage mounted at the moment.

I'm fairly technical so I can try most things anyone might come up with.

Thanks in advance!
