I took a look at that hi res feature. It was indeed on, although the music I was playing was regular AAC files. I turned it off and tried again but I noticed this time around that when I was changing the slider that the speed label on the now playing screen was changing as I scrolled, but was instantly reverting back to 1x. Almost as though it would let it try updating, but refusing to let that bind.
I did turn on the logs but I wonder if perhaps this isn’t capturing that action.
I’m thinking perhaps doing a full restart on the app (killing it) fixed this. I can see it working as expected when I have the hi res feature turned off for both hi res and regular files, and then it disables the feature for hi res as soon as I turn it back on. Thank you for the assistance!
