Hello, I have the same issue. After the firmware update to 1.1.9 I performed a full "swipe data/cache" in Android Recovery boot menu and rescannef my music library. Unfortunately, It did not fix the issue. What is strange is that after the swipe, some old files (logs, images, ...) remain in the internal storage. I can see them with ES Explorer. May be parts of old music database are there too. I have just tried to click "Database Reset" in the FiiO Music application menu itself and have rescanned the music folder, and it has fixed the issue !
