can’t add songs to library or playlist.

whenever i try to add songs to my library, the plus button turns to download (hinting that it’s been added) but they’re not actually in the recently added.

i also can’t seem to create or add song to playlist anymore. when i create new one, it’s loading and loading forever.

i tried resetting the app, redownloading it, tried it on other devices. it’s not refreshing at all. i am really frustrated because for the last few days i added new songs without knowing that they aren’t being added.
