Seems like since going to ios 12.1. most music I try to play on my iPhone 7 will start to play but will not finish. The green line shows that the file has not finished loading and of course playback will stop at the end of the line. I'm used to this happening with hi-res files over a cellular connection and understand that cellular bandwidth was probably the culprit. But what's happening now will happen with 16-44 flac files over wifi. Not a cellular issue. Wifi is connected at 2.4 and the problem happens even when the iPhone is the only device using wifi.
Is anyone else experiencing this? Is there a diagnosis? Is there a fix?
