Yeah, not sure how long that behavior has been there, but I noticed it has been very inconsistent throughout iOS 11. I’m guessing they are referring to something different as I don’t see much functionality to what you are referencing over just tapping on the tab.Hmm I wonder exactly what that means? I just tried 3D touching on a tab when all the tabs are showing on my iPhone and noticed you can peek and pop the tabs... I never noticed this before until I read your post. I’m guessing it’s not the same thing but I never noticed this on iOS 10.
