Why is instagram 'disappearing' from my iphone 4S
I am using iOS6.1.3.
Instagram just disappeared.
In app store, the update or 'free' button is faded, i can't click on it.
Have been through all steps on the help screen and synched via computer but the app loads then vanishes off iphone screen.
I assume i am not the only one, is there a fix?
thanks
