Resume the song from where it was left off before the app restart

The title says it all. It looks like Deezer restarts the song from the beginning if the app is restarted or if we switch between devices but this is very disturbing. I understand that it might be complicated to sync the location while switching devices but surely it is not rocket science to restart the song at the exact place after the app is restarted. The app clearly registers the last played song, it just needs to register the last location as well.
