I have noticed my top-bar edit notifications (that is, being notified when other people edit my posts) to be somewhat erratic for a while. Sometimes they're delivered and sometimes they aren't. I haven't found a pattern to it (if indeed there is a pattern). Some data points:
This post (on a per-site meta) was edited twice on the same day; I was notified of one of them
I was not notified of this tag-only edit in the top bar or network profile, but was on the site profile (I'm not sure if tag-only edits are supposed to notify)
All of these edits occurred within the last week. As I said, I've noticed, but didn't record, erratic behavior over the past few months. In one past case I was away from the site long enough that it should have triggered an email notification and that didn't happen either.
Are there circumstances under which I'm not supposed to get edit notifications? If so, what are they?
