When I login to Stack Overflow, in the Questions tab I see a tab for interesting questions. but it never appears when I go to another tabs and come back to the Questions tabs.
Why is it so?
The interesting tab is part of the homepage, not of the Questions section. Click the logo to get back to the homepage and see the interesting tab again. They're subtly different in more ways if you look at it, only the Featured section is shared.
The tab is on the homepage, not the
Click on the
Stack Overflow logo and it will be there.
