My music isn't downloading?!!

Currently my newest saved songs in my spotify account won’t load onto the djay app, I’ve tried restarting my iPad, re-running the app and still the last 15 songs under my playlist won’t show up on the djay app, I have a special event I have to dj at and I need those songs to load.
The last thing I haven’t tried doing is deleting the app and re-dowlaoding it because I don’t want to delete all the data I have saved with my other songs (cue. Etc) . So if u could please get back to me ASAP that would be incredible. Currently I have exactly 460 songs saved under my “starred” playlist and the next 15 won’t load, I’m not sure if there’s a limit your company has with the playlists or if it’s just a malfunction but if you could tell me how to fix it that would be great, please and thank you

Offline spotify is not alowed in djay.

I’m on wifi
