Need to fix the notification

I been using for almost a whole year and everything was great. I like the new interface. But, the apps stop giving me notifications and I miss texts that I cannot see. Fix it please. And, please give us easily to view time stamp of text when receiving and try to make the notification stay in notifications center, not disappear after receiving couples seconds. Now, I cannot receive text on time and get them very late. Fix that also too. I like the app.
