I think this just popped up as I haven’t noticed it before, but I have a few multi disk music albums and on each of them, track 1 through 4 seems to be hidden on each disk after disk one. Also when I enable the image header, there seems to hide a lot of tracks while scrolling.
Interestingly enough, all the hidden tracks do play regardless, and I have checked the same album in both the mobile app and the WinAmp Player. All tracks show there. This only happens in the web app. Currently, running it in Google Chrome.
