The issue on our end is fixed - comments on long-form posts published from context menu ("quote" etc) weren't visible - didn't have 'a' tag. But we've also discovered that other apps are having the same bug - Amethyst shows their comments, but we don't (and shouldn't). We've reported to Nostur and Nos about the issue.
I tried again to comment from context menu and it's not visible here: https://compilados.npub.pro/post/6wfgfewbqsorp9sri7qk4/
Hmm that's probably cache issue, could you please reload with Ctrl+Shift+R ? Thanks
