I’ve noticed a bug appearing with the latest version of AS. This happens on the Windows version, not sure about the Mac.
Normally when you listen to music at the bottom of the AS program window you’ll see the music information being displayed like this example.
However pretty often that information disappears while playing. Or it starts playing without any at all. Then it looks like this.
I stream most music, but so far I haven’t seen it happening while playing local files. Although I suspect it might be a common issue.
