wi-fi sharing: iPad was connected to Mac via USB. I selected wifi sharing, and then selected USB iPad. That failed, iPad still could not connect. Then I selected all options for wifi sharing, and it still failed. You may have a point on Secure Enclave. But, wrt 'a full restore' on iTunes, wouldn't I restore to factory settings? And then what? Are there people that did a full restore to factory settings and then installed the beta and had no issues? Because they way I see it, even with a full restore, installing the beta would still generate the connectivity issues. But if there are users that got rid of the connectivity issues on the beta by first doing a full restore and then installing the beta, I'd be happy to try that. Except that it's one of the few things I haven't seen reported.
Talked to someone on PM that I found on a different thread who did exactly that and it worked. But I don't know if it will for you of course.

I installed today IOS 11.3 Public Beta 2. The WiFi issue with protected connections still exist. Also the Apple ID verification is not fixed. Any suggestions what to do beside an IOS downgrade?
Reset all contents and settings fixes it
