I use a lot of chat apps on my IPhone SE. I use skype, hangouts, wechat, whatsapp, facetime etc. I do not know why but I do not get any ringing notification at all for any of these. I had checked my notifications and it appears that it is on for each one. Can someone tell me why im having these issues? I want to have a ringing sound for everything except messages which i would like to get a note sound etc.
