I can’t add music on my instagram story

Wrong deggie, I have the same problem and it started immediately after I did an iPhone update. Definitely an Apple issue as said on a Spotify website. And yes I pay for my music. Sharing has never been an issue before.

Hey man the problem is most likely in the application itself, try to upload the app it usually helps. Problems with instagram occur very often I think everyone has experienced it for themselves. Once I had a problem with video uploading after using https://igautolike.com service but as it turned out it was just necessary to update the application. As you can see everything is easy and simple especially when you use iPhone))

Well, Instagram isn't and Apple app so it might be a question you want to direct to them.

Also, is this music from a subscription account or music you have actually purchased?

You can't share purchased music. You can only share what you create or own the copyrights to.
