I'm a premium user and have been for a very long time now. Few months ago, the repeat button on my Spotify account has been unable to use on my iPhone. Basically the button is there, but I can't seem to repeat a song, although I can repeat all the songs in the playlist. It's still available on other platforms, just not on my iPhone.
I'm a premium user and this is one of the features I am paying for, so I think my inability to use it, just means you aren't really providing the services you advertise. It doesn't matter if I'm using the oldest phone or software. The problem is, it was once there and it isn't anymore. So, can you please do something about it as this is beginning to annoy me.
