I can't connect to campus WiFi anymore after installing latest ROM with december 2020 security patches. The configuration is PEAP/MSCHAPV2. Under CA certificate, we usually choose "Do not validate" but now CA certificates is set to "Use system certificates" and can't be changed. "Use system certificates" setting requires Domain name which I don't know and have never needed to use before in any ROM.

Is there any workaround to choose "Do not validate" in "CA certificate"?
