Yes, indeed. My iPhone 6s has been flaky since upgrading to OS14 and began having intermittent problems being unable to connect over Wi-Fi, although connection via cellular was just fine. I read many suggestions of power cycling the phone, re-setting the device, airplane mode, location services, find a shrunken monkey-head, etc etc and became so frustrated that I finally wiped it and reinstalled the OS to try to fix the issue, without luck. Believing it was a hardware issue and maybe the Wi-Fi chip was bad, I was preparing to bite the bullet and find a newer phone. Then I stumbled on this thread.... I turned off the "Private Wi-Fi Address" feature and voila ! - everything is back to normal since yesterday..... https://support.apple.com/en-us/HT211227 YMMV - good luck.
