Missing Whatsapp Icon Iphone 6s
I have been reading about other posts on this matter and tried everything indicated but with no success.
Basically I installed Whatsapp (new phone), used it a bit, returned an the icon is no longer where I placed it. When I go into AppStore it shows as a purchased item with an "open" button. When I open it, nothing happens.
I have done the reset, restore options as indicated by others with a few other tricks as well. I have had no success.
Can anyone shed light on this problem
iPhone 6s, iOS 9.1
