MacAir doesn't show up on FindMy app

I have made sure the Mac FindMy feature is enabled by checking Settings, account, saved to cloud (click all), FindMy. Computer shows it's ON and Location is ON. Then checked Location services under Privacy. Location is ENABLED and FindMy is also ON. And yet my other Apple devices don't show the Mac on the device list. Rebooted computer. No change. Looked under Settings/Account on my iPhone 16 and it shows the Mac but when selected, shows the FindMy feature is OFF. How do I resolve?
