I had (and used) karaoke mode. I sang one song that wasn’t supported by this feature (without scoring) and then one that did have scoring. I wanted to try another song, but I couldn’t find this feature anymore. I tried a lot of different songs, but the lyrics all just looked like normal lyrics, meaning it was like before I’d seen the karaoke feature. My device is an iPad Air 5, and I’m on the newest version of Spotify. Apparently not everyone had access to the karaoke feature, but it’s weird that it was there and then went away?
I'm having the same issue. I had yet to use the feature, but saw that the karaoke mode was available for the majority of the songs I'd listen to. I first noticed it on my Samsung A51, but when going to check it out today on the same device, the mode had all but disappeared. My guess is that they made it available for some people initially, and took it down to work on it. That or they're switching up who has access until they do a full release. Anyway, I hope they reinstate it soon, I would really like to check it out!
