How to fix Wifi screen sharing/Airdrop issues with Smart TVs on MacBook

Ever since updating my laptop to the Sonoma version, I've been experiencing a couple of issues. Firstly, when I attempt to share my screen to my Smart TV via Wifi, I receive a message saying "Incoming connections blocked to TV." This is a new problem that I have never encountered before.

Secondly, while I can see and share files from my laptop to my phone using Airdrop, but I am unable to do the same from my iPhone to my laptop. My iPhone does not even see my laptop in Airdrop. This inconvenience is frustrating and I transfer files via email between my devices as we do in 10 years ago.
