Downloaded songs don't play when offline

As described by many other people, I have downloaded songs that don't play if my phone isn't connected to the internet. My "Favorites" are marked with the green check ✅ when I go to the downloaded section, but every time I'm offline and I press play the music loads and then lets me know that I'm in Airplane Mode or that I'm having network issues and that it can't load the content. 

This issue has to be fixed 🙏🏼
