I have a number of albums on my iPhone 15 Pro Max that were put there by a third party app (MediaMonkey).
I've just installed the Public Beta of iOS 18 on my phone and MediaMonkey doesn't support that yet for updating.
I've tried iTunes and the Apple Music and Apple Devices apps on my Windows 11 machine but have not been able to "see" the actual music that's on my phone. When I select Library or Music, I see music that was on my wife's account a couple of phones ago.
Any suggestions?
