I've reported it (I can verify the CRL check either failed or the CRL does not include the CA certs). No FB number was provided.

For me I had to go back to the feedback assistant home page, refresh (swipe down), then it showed up under 'Recent activity'.

How did you report it? If you used Feedback Assistant then it would have given you an FB number. That’s the only way to be sure anyone at Apple sees it.

I selected the applefeedback:// url you shared and used "look up" (there's no "open link" option). That sent me to the official Apple feedback site. Are you saying that site's submissions aren't checked or something else?

No, that’s the right path. Your report should have an FB number.

Ah well. Guess it's as broken as the CRL, or I just clicked the buttons wrong or something. I just saw a thank you screen. I checked my email in case they sent something there, but nah.

The good news is that Safari finally stopped loading the certificate test page I've been using: https://dv-g3b-emudhra.we-have-a-problem.com/
