Sharing my iTunes library - worked, but stopped
I have a mac M1 Max studio, Sequoia 15.3.1, with a 1TB iTunes Library I built over many years, on an external drive. My wife has a macbook and listens to my library when she is working in our home office. It worked fine for a number of years, until Mar 1st, 2025 - and now she can't see my library on the network. I don't see the SHARE button in iTunes. We do not subscribe to Apple Music.
How can I get this working again. I don't see a way to add her "device" to my account. It shows we have 4 devices authorized, but doesn't show what they are.
