Yep. I had uninstalled Qspot for a few weeks, installed it again when you announced the update, but I somehow installed the 1.1.1-2 version as previously stated : it didn't load any playlist (as expexted). Then installed the 1.2.0-1, and it worked: as far as I know it loaded al the playlist but I didn't paid attention to track numbers to every playlist. I only tested a one-track playlist I have (...), and playback worked...then went to sleep...
A full day after I tried Qspot again, and I got the 0-track playlist problem. Unfortunately I don't remember installing or removing anything on my device during these ~24h but it could have happened...
