IPhone deleted my snapchat app, can't get it back?

So since iOS 8 came out recently, I guess all the apps required an update as well. While I was updating all of my app, my phone removed snapchat. So I went to the App Store to try and re-download it and it only shows the "open" option as if the app is still on my phone. I clicked on "open" and nothing happens.

Not quite sure how I can fix this. I tried turning my phone off and back on again to see if it will reset it, but that didn't work. I would really like to get my snapchat back since I use it often. Anyone know how to fix this?

I would just search for "snapchat" in the App Store and reinstall again. Not much you can do anyway

Nevermind, I figured it out. Went into settings > general > usage > snapchat and deleted the app there and then reinstalled the app from the App Store.
