i noticed the last two time i used Spotify that the singles section on an artist page on the Spotify app for Android is missing. 

for example, on Metallica's artist page, it show the New Releases, Popular, Artist Radio, Related Artist, On Tour, Albums, Singles, Artist Playlists, ETC. 

usually, i would find the singles on the page with all the singles relases. but it's missing right now, i can't access it, if i want to find a song on a singles part of the site that isn't on an album right now, that means i have to search the song either by name or the name of the singles album it's in (which should be the song's name in somecases) 

the version of my android device is Android Lollipop 5.0

my device is a RCA RCT6773W22B

and the version of the Spotify app for Android is 6.9.0.1212, which i downloaded from the Google Play store.
