My Question or Issue

Recently, I switched over to an Iphone 11 Pro from Iphone X. I like to download songs that are not available on Spotify from youtube and put them in my playlist and before, on my iphone x it would just automatically synce from my windows onto my phone. Now, it seems to not work anymore with my Iphone 11 Pro. The titles of the song dont even appear in my playlist, theres nothing there unlike many people who have the song but its title is just blacked out. I am on the same network as my PC and I have uninstalled the app and logged out from my old phone. Please help thanks!
