You’re welcome :) If you’re not afraid of making your HN addiction worse (and can tolerate some amount of jank), it’s not hard to set those up using https://hnrss.org/replies?id=NetOpWibby and an RSS-to-notifications mechanism of your choice (in my case, https://t.me/el_monitorro_bot; there are a few RSS-to-ntfy.sh daemons around as well if that’s more your thing).
Thank you for taking the time to let me know about these bugs, I'll check 'em out!
