Music appears on my desktop but not on my iPhone after syncing in iTunes.
On the desktop, 2939 songs appear to be on my iPhone 13 Pro Max. when I finish syncing or applying the number drops to 1296. I just the music which has been on all of iphones and in my itunes since 2008. No subscriptions (or wanted or desired) as I already have paid for all of this music. I just want to listen my music like I did before this occurred. I have most all of the physical CDs on premises just for an occurrence such as this. I also have screenshots and photos of what is happening.
