iPhone remote app not connecting to AppleTV

Over the past few months, my iPhone remote app, in the Control Center, does not work to control my AppleTV 4K. Also, screen mirroring also works 50% of the time. Sometimes it works, and sometimes, it will just spin and then say cannot connect. But the remote app only works maybe 20% of the time.

I have check all wifi configurations and am only using 1 wifi network/SSID. All devices show up in my Device Manager in my Wifi router.

I can see many others have this issue, it seems most likely related to iOS 18 updates. This is very frustrating to have no fixes for this.
