Same issue here. Both my iPhone 12 Pro Max, and iPad Pro 11-inch (2nd generation) are experiencing a wifi issue after the commercial release of IOS 17. Getting error messages from multiple apps saying I am not connected to the internet. Settings show I am connected to my wifi, but the status icon next to my cellular strength is missing on both devices. I have restarted both devices as well as my wifi router with no luck. How can a major OS release miss something as basic as the ability to connect to the internet? Apple please fix this ASAP. No user should have to deal with this.
