I've been using "Find My Friends" up until 2 days ago. Now, everytime I sign in with my Apple ID & password, the response is "Connection Lost You aren't connected to the internet. Please connect and try again." Of course, I am connected. Others work.

"Find My Friends" app stopped working. When I call it up on my iPhone 4S, it asked me to sign in with Apple ID & password. Then it responds with "Connection Lost. You aren't connected to the internet. Please connect and try again. OK". Of course I am connected to the internet.All other apps are working and I can use Google, etc. I have deleted the app from my phone, my iTunes and reloaded. I still get the same result. Where do I go from here?
