My friends list has just started to not update correctly, I have reinstalled spotify and the issue does not seem to resolve itself. I also have restarted my Mac multiple times and this has made no difference.
I know it sounds simple, but it's often overlooked. Could you try restarting your device? Sorry if this may sound a bit repetitive but if that doesn't help, try a quick clean reinstall of the app by following these steps.
I'd also recommend updating to the latest version of macOS Mojave. Have you tried it with another internet connection to see if that helps?
If you're still having trouble, could you let me know the exact version of Spotify and the exact version of the operating system you're running?
I'll see what I can suggest next!
