Okay. I am sending my report now.
The first image is the screenshot from my site, the second is the screenshot from ZeroSSL (which also applies to Community, and the other non affiliated sites).
It appears as though all sites are now showing me the intermediate certificate. At this point I’m confident it has to do with a Safari bug. This is odd because just a few hours ago, my site was showing an April 24, 2017 expiration date.
EDIT: I decided to test some websites that were secured by other CAs, and they too are showing this error. I am updating my report to Apple.
