No longer getting email notifications for Announcements [Stable Updates]

The last 2 or 3 Stable updates, I’ve not been receiving my “First Post” notification by email. I used to get both email notification as well as the red circle notification icon in the top right corner of the forum.

I simply assumed that the forum software no longer provided that function. However, today I received email notification for a new Update Announcement post in Stable-Staging.

Is email notification still provided for normal Stable Update announcements? Or was there some glitch in the software and now email notifications are back for all marked categories (I only marked Stable and Stable-Staging for notifications).
