Which iOS version? 27.0.1 here and they're all revoked for me.
26.7.1 still (randomly) trusts 2 out of the 12 compromised chains. All browsers impacted.

My best guess is it's soft-failing on a failed OCSP lookup?
FWIW i havent updated my ios, I'm on 26.6.2, and they all got revoked for me. The revocation shouldn't require an iOS update.
26.7.1 still (randomly) trusts 2 out of the 12 compromised chains. All browsers impacted.
