Apple Music Undownloading Songs From My Library

I have always used Apple Music and have over 2,300+ songs. The app is constantly undownloading my songs so that I am unable to listen to them offline. My optimize storage is off, my sync library is on, and I have plenty of storage left on my phone/MacBook. I have seen many Reddit posts regarding the same exact issues yet the only option I have seen is to add every song I own into a single playlist so that I can download them with a single click. I am currently trying this out in the meantime, but it is taking forever for the playlist to actually download due to how many songs were undownloaded over time. I have thought about switching to Spotify to see if that would solve my problems, but I would rather not have to do that. Any ideas?
