No notifications on threads involved

I’ll start by saying I am not an admin of the GitLab CE instance, just a user.

I am trying to understand the notifications logic (not emails, regular notifications).
My global notification level is set to “Participate”, and all my repos are set to “Global”.
Yet, I do not receive notifications in those 2 cases:

  • I did a merge request, and someone commented on my code.
  • Someone replied to a comment I wrote.

In both of those instances, I expected to be notified but I wasn’t.

On the other hand, I correctly get notified when someone mentions me, or when I get assigned a MR.

Am I missing something?
