I don't see it in the mobile app either.
I know where it should be as I play on my laptop and I see it. I checked on my iPad, though I no longer play on it, and it isn't on the app.
Thanks for the confirmation, guys.
Frankly speaking... I, as a mobile player, feel totally discriminated every time I see the functionalities of PC are not equally applied for the mobile version.
I know it is what it is, but still... :-/
