16.4 update and Classical app breaks airplay to HomePods
Since updating to 16.4 and adding the Apple Classical app, airplay from the phone no longer functions correctly when using the Classical app. Music only is produced from one of a stereo pair HomePod (1st gen) set up via airplay. On the other hand, streaming via airplay of classical music from the Music app on the phone OR desktop works correctly as it always did with both speakers producing music.
Something seems broken with the Classical app or the 16.4 updates to HomePods and iPhones.
