As many have noticed the feature where you receive and email when someone replies to your comment has disappeared.
It was replaced by the Coral group due to complaints about the feature. Unfortunately, they didn’t bother to mention it to anyone who didn’t contact them @ Coralsupport@voxmedia.com. That’s where you can give constructive criticism about the platform.
The feature was replaced by a Bell tab. If you go to the comment section of an article, it’s in a couple of spots, depending on if you’re on your iPhone, iPad, or laptop. Those are what I use so you may have to search a bit.
