I too am glad I checked here. I wasn't sure if was hardware related. I just upgraded to iPhone 12 Friday. My "old" iPhone 11 was running iOS 14.1 but didn't seem to have the issues I'm seeing with the new phone, also running iOS 14.1 naturally. Hello, Apple... we have a problem!

Found this hack... and it appears to work. Give it a try! Open the Settings app, then go to “Wi-Fi” Find the wi-fi network you’re connected to, then tap the “I” button next to the network name Tap on “Forget This Network” Exit out of Settings Turn on AirPlane Mode by pulling down Control Center and tapping the AirPlane icon (or by activating it from Settings), leave it on for a few seconds, then turn AirPlane mode back off again Return to the Settings app and go back to “Wi-Fi” Re-join the wireless network you were previously connected to.
