Good idea,bad performance

Really good and interesting idea that you can send your picture,video or just text to random people(from 5 to 50) and that they can answer you.Bad thing that sometimes you see new message,open it and it doesnt work,only application opens,but not message.And that you cant delete messages all together,only one by one.Please do something with it.
