Download button goes missing

[u/P_Devil]

My download button always goes missing. I will download my liked songs playlist, the button goes missing, and I can't download new tracks in that playlist. The only way to get it back is to delete the app and reinstall it. Force dropping doesn't work and neither does restarting my phone. I even gave Amazon Music unrestricted battery usage.

Adding more songs doesn't work either, they won't get downloaded. Why is this service so buggy?
