After upgrading, i noticed that Find my Friends icon is not on any of my home screens yet in the App Store the option says "Open" which means it is installed in my iPhone. Checking the General > Usage > Manage Apps, the Find my Friends is also listed there. Already tried deleting the app from there and from iTunes in my computer then sync which is fine but when i try to download it back again from the App Store, it loads on the home screen but after it says install the icon will vanish. The only way for me to open the app is by clicking "Open" from the app store. Already tried Factory restoring the iPhone, even to the extent of downgrading back to 7.1.2 then upgrading OTA but still the same. The app installs fine though in 7.1.2 but after the upgrade, the icon vanishes. Anyone else having the same problem? My main issue aside from the missing app icon is that the Share my location feature is not enabled in my messages, even the map won't show up. I think its because there is a problem with the Find my Friends app in my phone.
