After updating 13-inch iPad Pro (M4, 1TB, cellular model) to iPadOS 27 Beta 1 and later version, the automix mode in the Music app has stopped working. I have confirmed this issue is unrelated to my subscription status. I tried toggling the Song Transition option back on in Settings and switching to the Crossfade mode, but the problem persists—the Song Transition button inside the Music app remains grayed out and unavailable.
