I am on Android
While browsing the Stacks Exchange(app is the latest version) Data Science using my smartphone,
Just switch the Questions to Users And then Revert back using the back key of the phone,
The feed changes to again display the recent Questions but the header still shows that it's Pointing to Users Section..
Moreover if your in the second state and select a Question to read or answer, And then again press the back button, You are directed to the Users Tab but I Should have got directed to the Questions tab
Sorry for my English if it's making it look Complex...
