I am no longer receiving notifications or emails when someone replies to my comments. This makes it difficult to keep a conversation going. For instance, I commented here (and received an email about the necromancer achievement), but have not received notifications or emails when Kenneth replies. All check boxes are checked under Settings > Notifications. My spam folder is empty.
While I have your attention, I'd like to mention that the "reply" button is (still) missing on recent comments in threads. See below:
If I right-click and inspect the web page, the reply buttons appear (this has been my main workflow for a while now, and it's getting old fast).
Check whether you have enable the notification for getting alerts when any new comment or a reply is added to the page? This can be the case and you just have to click the more button right next to the like button to check whether the option is on or off. dissertation help
