Spotify Connect missing wifi speakers on Mac desktop

[Idaknowa]

I have a Premium Family account in the US and use Spotify on multiple devices including my Pixel 3, Google Home, Google Home Mini, and 3 wifi speakers (2 Vizio and 1 Marshall). All devices are fully up to date and the Spotify app on all playing devices are fully up to date.

My problem is I can't see any of my wifi speakers, except my Marshall speaker, or Google Home devices from my Mac when trying to play over Spotify Connect. It also does not find any of the "rooms" I have setup in my Google Home app. All my other devices including my Pixel 3, my wife's iPhone 8, 2 tablets (Samsung and Fire) and both Google Home devices detect all the devices and rooms. I only have 1 wifi network and all the devices are on the same network.

Any help with why I can't connect to any device except my Marshall from my Mac would be greatly appreciated.
