So? How is that relevant? Did Apple promised that it supports it but it turned out it does not?

"Just works, as expected", except when it won't play audio from another Apple product.

I don't know why you are so bitter. Did you bought it, failed to play and Apple refused a refund? Where the anger comes from?

PS: It actually does play whatever sound you play but it wouldn't transfer it as a lossless since bluetooth can't handle those bandwidths.

BLuetooth has not enough bandwith to handle that lossless audio with overall good experience, is my best bet.
