Find friends not working with ios7

I tried the delete app restore iPhone and add app with no luck on Notifications on FindFriends.

Like everybody else it used to work and now not a peep.

The Apple store I visited knew of the issue and gave me a fix that works. Plug your phone into your MAC, do a full backup and restore. This will restore the iOS on your phone and put everything back exactly was it was. It doesn't take all that long and worked. I did this and I get my notifications again. Nice. Just backup the phone and do a full restore....
