Apple’s new Private Relay is leaking your original address through WebRTCQuote
If you perform a test with Private Relay turned on at step Reflexive connectivity you’ll see your address from your ISP. If you connect through a virtual private network or proxy and try the test again then nothing is leaked. I have reported this bug to Apple. Just to be aware, for the users under us.
Edit: workaround is to enable WebRTC Sockets Proxying under Experimental WebKit Features. However In-App Safari will still show the leaked address even when this is enabled
