App glitch

Hello I'm having a problem with one of my apps disappearing, it needed updated so I did so, along with getting a couple of more apps, but when I went to go to the app it wasn't in the folder it was assigned. So I looked around and it's no where on my screen and when I looked for it in the store I couldn't find it either. So I went to my purchased apps and it says its installing it but I can't click it at all.



I deleted the app, turned of my iPad and reboot it also, can someone please help?
