Top quiz

I am really enjoying this game but when I look for it in my apps I can never find it! If I search for it it will show up since I downloaded it several weeks ago but it wont stick in my iPad apps for some reason.
Have you heard of anyone else having this same problem?
I am challenging friends but have no idea if they have completed their challenge or not.
Please look into this and let me know. Perhaps we are only allowed so many apps on the iPad ...I dont know..

Thanks
