Spotify Connect - need premium subscription?

[#1]

Hi all - beginners’ question. I want to use Spotify Connect on my Ruark R3s, which is equipped for this. It worked for about a hour with my free Spotify subscription, but now, when I try and select the device in the Spotify App on my iPhone, it says “Ruark R3 - premium required”. Is that normal? Why would it first work with the free subscription? Many thanks!

My Question or Issue

The Wiim Mini has Spotify Connect. Do I need Premium to use one? Or will it work with Free?

What about with older stereo receivers?

I did the log out and back in twice, but I still can't use Spotify Connect on my Yamaha R-N301.
