Just realized that my phone is no longer automatically picking up the Wi-Fi in my home. I was able to get it by bring my phone next to my wife's iPhone XS Max which does automatically pick up our home wi-fi. She refused to upgrade when I got my iPhone 13 Pro Max and, unlike myself, has not had any issues with her old phone after updates.
