Hey @yen! Welcome to the Spotify Community. ^^
First of all, what device are you using to run Spotify ?
On the desktop version you can find the Spotify Connect icon on the right side of your client.
Hope that helps. ^^
You can find Spotif Connect in almost the same way on the iPhone. ^^
Hey there you,
Yeah, you! 😁
Welcome - we're glad you joined the Spotify Community!
While you here, let's have a fun game…
