This question already has an answer here:
I no longer receive notifications (both on web and iOS app) for edits made to my posts by others. If I recall correctly, this didn't use to be the case previously. However, I can browse to the Responses section under my account overview page to see the notification listed.
I have first observed this behaviour a month ago. I would like to be notified for any edits made to my post(s).
Has something changed recently on the website? Or is this possibly a bug? Has someone else observed it too?
