On MBP, the native banner/notification that pops up when the playing song has changed (e.g. after the previous one finishes) appears to be delayed by anything from 10-30 seconds. Funnily enough, when I hit the backward button (to restart the track) after this has happened, the issue appears to fixed thereon (i.e. the bug is no longer reproducible with subsequent song play). I suspect it may be an issue just when a music player (or dps) is initially launched/activated, which then remedies itself after a backward or forward skip is performed.
e: I spoke too soon perhaps a different or related bug: A song began around 30 se(i.e. the song jumped 30 seconds ahead of the next song . I’m gonna deactive dps and see if this reoccurs.
