Whenever I sign in on Instagram (desktop or mobile versions), numbers appear on a red label.
The one shaped like a head and shoulders usually means new people are following me since the last login. The one with a comment bubble means new comments since my last login.
But the one with the heart does not mean the number of likes since my last login.
I have never seen the number be higher than 99, when most of my posts get around 50 likes in a few hours. This morning when I logged in the heart number was "39". I manually counted the likes for all 14 photos I posted yesterday and the total of likes is 421.
Is this a bug? What does this number mean?
