I am facing exactly the same issue since myself and my wife upgraded to 16 plus and 16 pro.
Simple google search unable to load on WiFi on our phones while Netflix and any OTT platforms are running smoothly on TV through the same WiFi. I have to switch back to mobile data. Not just WiFi at our home. Same issue when trying to connect to wifi elsewhere. This is super annoying issue and I am surprised how Apple let this level of critical issue posted here sometime back, no one responded..?? Hmm may time for X phone
