I was recently awarded a new badge but didn't receive notification for that in inbox. I observed that in the two recent badges that I was awarded.
Is this the default behavior on Meta or something is not working?
The following bronze badges notified to users:
Nice Answer Nice Question Caucus Excavator Mortarboard Popular Question Proofreader Revival Synonymizer Tumbleweed Vox Populi Announcer Precognitive any tag-based bronze badge
other bronze badges are not notified to users.
