spotify issue

hi all
I have just switched back from android to IOS, and am having an issue with spotify.
In android, when casting audio to a nest audio, which you can also do with an iphone, there was a really cool feature, whereby, when you focused on the song that was playing, and flicked left or right, you could go forward or backward a track, respectively. This was regardless of where in the app you were. I am told by spotify customer care, the feature is available on IOS, but after multiple uninstalls and reinstalls, I just can't seem to get it to work?
I'm hoping one of you very many more knowledgeable people here will be the answer to my conundrum
With thanks in advance
