Basic beginner questions

Guys, This is probably an easy fix but I’m looking for advice.
I’m a ps3 player and think I’ve downloaded the latest version but,
1, Zlotun K is nowhere to be found so I can’t get Kanais cube

2, I’m paragon level 40 crusader and have done about 15 rifts and still haven’t got a greater rift keystone…

What’s wrong??

Thanks in advance for any help!!
