I observed this behaviour on each of the recent daily builds…
Platform: FuzeV2
#1: After playing the last song in a playlist, the thumbwheel appears to be stuck. I have to actually press either the wheel or the home button before I can use it.
#2: When changing stations in the radio screen, the name of the current station (stored in a preset) does not show up. Instead it still shows the name of the station that was active when I first entered the radio screen. This happens when I press |<< or >>| to change stations, but not when I use Home to access the complete list of stations.
