Queued YouTube Videos

I'm running an I-Mac running Ventura 13.1. When I set up a video queue, it will not automatically play the videos through my Chromecast device, but it will play them on the computer. Autoplay is on. Youtube support has no idea what's going on. Also, my Ipad and my iPhone will play the queued videos automatically. I'm thinking something is off with the Ipad, but I have no idea what it could be. I can't be the only person on the planet with this issue. Any suggestions?
