The app is not working properly from past 1 month. It suddenly hangs while using and then it closes, the chats i sent 2-3 hours ago are still not sent, i checked my internet connection and it was fine but still after many attempts my chats are not sent, i updated the app but still i am facing the same problem. Once there was a time when snapchat was my favourite app but not it really gives me headache as it doesn't work properly anymore and just keep on hanging.
