I like the numbers that appear on the tabs in my profile. But it seems that they don't always work, at least for the favorites tab. More than once (many times really), I've clicked the tab to find highlighted activity, yet there was no number on the tab. The number isn't very helpful if I can't depend on it. I'm now in the habit of clicking on every tab every time I check my profile.
Has anyone else noticed this? I'm not sure if this happens on a particular site or not. I haven't noticed a pattern.
Is this feature implemented across all sites? Is the number only calculated at certain intervals? Is there a bug?
Note: I searched before posting. I found several posts explaining what the number means, and several posts explaining how the number is calculated. But I didn't find anything about its random appearance.
I already know what the number means. But it doesn't always appear even when there is new activity. Sometimes, I click on the tab and notice that several of the entries have a different background color, indicating that there is new activity. Yet the tab has no number. If I hadn't clicked the tab, I would have never known there was new activity. Next time it happens I will post a screenshot.
