FaceTime not working after last update/mirroring iphone

my Facetime does not work correctly on my macbook air 15 after the last update. I can call and except calls but when i go to answer the call it either wont answer or you can still here it ringing. I feel like it has to do with the iphone mirroring option that i expected on the last update, and i have disabled it on my iphone like it says to, to see if that would fix it but it did not.

anyone else having this issue.

JUST NEEDING HELP UGH
