Love but we’res the pin post?

I love this so much I met some of my best online friends here and I’ve been using g+ and hangouts for the last 2 years. Me and my friends are celebrating our first and 2nd year or knowing each other! Although I’m having difficulty with the pin post thing.i hate that there isn’t that option on iOS. And I really want it for my iPhone because everyone else has it but I don’t and it makes me feel left out a bit. So please add the pin post mechanic
