Safari 17.3 won't play videos from Kayo Sports

Safari 17.3 on macOS Sonoma may have compatibility issues with Kayo Sports. Try using a different browser like Chrome or Firefox, or check for any available updates for Safari and Kayo Sports.

No luck with Sonoma 14.4 and Safari 17.4 either. I have asked Kayo what their problem is.

Yeah, same here. Safari used to be such a good browser but over the past 3 years, has degenerated into a POS. I tried Google Chrome (only) and Kayo is fine.
