Hopefully, members who are experiencing this problem will reply soon as well as reply with a remedy. In the meantime, make sure you have the latest version of the app and don't hesitate to peruse the app's support site for answers.
iOS 9 with whatsapp have the same issue, message delay 5-10mn before been delivered, not all the time but most often. Now I thing it's whatsapp server issue and not the iOS or the application it self.
