Greetings BrianRisi,
We’d like to have you check on your login. You profile shows that we’re working with an iPhone. In Settings > your name > Media & Purchases does it show your Apple ID here as well?
If not, you can sign out of the Apple ID that shows here and then in with your Apple ID. If it does, show your Apple ID here, we’d still like to have you sign out and back in just to refresh that login. Then test the download again. Signing out of your Apple ID in Settings > your name > Media & Purchases will remove any music downloaded with an Apple music subscription. Though it can be downloaded again.
Thanks.
