Spotify registers new offline device on each Galaxy S2 restart, which after 3 restarts (3 devices resgistered) results in unsynchronizing all content (then start syncing everything again). Particularly nice feature when you're on vacation... plus a nice utilization of CPU and network in geneal. C'mon guys please fix it, otherwise the app is not worth the money in my case.

I'm not removing the offline devices from my account so you can check your records.
I've seen this a couple ot times and the usual solution is to remove all the offline devices and start over. However, if you prefer not to do that, get in touch with the support guys here. If you get an automated response directing you back to the community or to the help pages, please reply to it by email and you will hear back from one of the team shortly.
