I would like to give 5 star over all.But yesterday this app was completely bad. It just didn't work for about 2 hours and none of my messages were delivered. Also this happened sometimes back and all the 20 messages delivered at once. Not sure why is the performance of thiz app going down. I want this app to shine better than other useless apps. I find this is user friendly and can have secret chat with friends. So  please fix the issue. Thanks in advance.
