Greyed out songs

So I haven’t paid my Apple Music bill just for a couple weeks and I finally did. Once I started using my music again, I noticed SO many of songs are greyed out and show that “item not available”. And I don’t think it could be a pre-lease problem, or the music/album is outdated. I saw that even Ariana Grande’s “Thank u, next” is greyed out as well and with that being said I’m confused as to why that song which is “new” is greyed out. Also I updated my phone to the latest iOS. Even some of my most favorite songs are greyed out which I’d like to get fixed. Anyone know what seems to be the problem? Please tell me because like I said, some of my favorite songs are all greyed out and I don’t understand why.
