iPhone is running the latest. Home sharing is enabled on both, as well as Apple TV which works fine. Same wifi, same Apple ID and signed in. iTunes on the Mac is open.
I cannot stream content to my iPhone from the Mac. This is not content I purchased from iTunes.
I bring up the Music app on the iPhone, My Music is selected. Nowhere do I see Categories that according to an Apple support article, should be visible.
What have I overlooked?
