Unsave From Android Notification Bug

[absentspace]

The unsave button does not work in the Android Notification pane. You can tap the + symbol, which becomes a √, indicating the track has been saved to your music. Tapping the √ should remove the song, indicating the change by returning to a +, but it does not. Please fix this. It has never worked in the 2+ years I've used this app on Android.
