McAfee alerted me my Social Security # was found as part of TMobile breach

Anyone have an explanation why I can't log into the McAfee account profile set up for the T-Mobile Breach?  It wants me to update my phone number, then says page may have moved...nothing there.  On second and third attempts it quit responding altogether.

Yes, finally convinced my husband to freeze his reports as well.  It's very unsettling.  The reason I wanted to get on is to find out how my credit company alerted me to the SSN being on the dark web late January, just in time for Ukraine, and why McAfee scan has not detected it?  Did I NOT include it in my McAfee account profile info to scan?  I have no idea if I can't open my McAfee account that seems to be notifying me of this monthly of a scan.  It's out there, yet I can't get in it nor find it!!!
