Can't connect my macbook pro and iPhone to apple tv?

I've been using my apple tv in connection with macbook pro mid15 and iPhone 6s for long without any trouble. But, and this is the only time reference I can identify, since last updates (end of may and june) I cannot do it.

In the apple tv configurations look ok (same network, etc)

in the Iphone the app REMOTE can't "see the apple tv and through the iPhone console I'm able to establish connection but it doesn't work.

In macbook there's no way to mirror the screen, even the icon on top disappear ?

I've rebooted everything? update today all the software (02.06.2020) hoping that it could be a bug of previous release but nothing changed!

Does anyone no something about this ? Thank you in advance
