"Oldest" shows on Windows using Chrome for me.
It doesn't show up here with either browsers, probably region factor (I'm not in the US).
I really hate these services (especially the mega ones like YouTube, Twitter) ALWAYS have random feature disparity across client/region for no apparent reason.
I understand they can't be exactly simultaneous for technical reasons, but often times features would be delayed in some regions for days if not months.
Oh, I'm on Windows too but using Firefox.
