iPhone and iMac mirroring issues

I love the iPhone mirroring that is available on my New iMac that I got almost a month ago and I ran into some things

there are times I can't mirror even even when I lock my phone to mirror and still can't some times

even when I restart the iPhone and my iPhone is iPhone 16 since I got it in January 2025

I wonder what those issues that preventing from mirroring and also when I get a phone call that will hinder after the ring is over when I don't answer

even when I do the revoke and restart sometimes it will not connect to my iPhone

hope to find how to resolve that so I can mirror

second and how to keep the mirror on for a while instead of timing out I guess and I had to reconnect each time and I like to keep it running so I can continue to listining on my Spotify for hours and not have to deal with re-engaging

oh if it is possible can I be able to see my apple watch too

and any input and I would thank you in advance
