I'm having the same issue. Been having it for almost a month now. Just reinstalled the spotify app and the issue persists. Even on extremely popular songs (think rap god or the weeknd's new album), or songs which I recall had lyrics before the issue. Now none of them have lyrics.
My Spotify had the same problem (iPhone 7). I've tried many reinstalling and etc but still doesn't work. My brother's iPhone (iPhone 10) have the lyrics, so i try login in his iPhone and the lyric doesn't appear. I ask him to login using his account in my phone and the lyric appeared. Then i tried login again using my account and suddenly the lyrics appears.
So try using someone's account that his/her phone has the lyrics, then try login using your account again.
Surprisingly this works! Thank you. I log out from my account. Asked my husband to log in to his account on my phone. (He has the lyrics on his phone). And log out. And try to log into mine. And walllllaaa! Thank you again!
I have two accounts. The other worked with the lyrics but when I uninstalled it, it never worked again. I understand that lyrics may not be available for other songs. But I played the song where I can see the lyrics before it stopped working and it's not even available. So the lyrics feature completely stopped. I already reinstalled the app on my mobile phone but the issue is still the same.
What did you sign in with? Previously mine was FB login. Changed to normal login (email/username) & password. Once done I used my friend’s account (with lyrics) to sign into my phone then logged out and logged in back to my account and there it is i got it!
