Seconded! Currently it's really hard to reply to comments from email without the consistent URL forwarding. The email links are still taking you to http rather than https, so I either have to copy the link and edit it before going to it, or I have to go to my journal and go to the post manually.
it seems like it. there is no rhyme or reason. comments to some entries are perfectly fine. comments to others still have "insecure" warnings. even from a brand new journal.
