iOS 12 tapping on notification to open app not working I've been looking online and I haven't found any articles about changing this on the new iOS update. Ever since I updated, it has the cool new feature of grouping notifications. 

My biggest issue is that I can't tap on an expanded notification to open that app. As in, if I get a text, I can't tap on it to open the messaging app to that text message. I have to either go open the app and then the text or use the mini-preview of the message, but this isn't an option for every app. I have continued to play with the notification settings and I can't find a solution for this. Does anybody have an idea?
I had the same issue and then realized that after I’d reset my settings my Face ID wasn’t set up. After I set up Face ID, tap to open notifications started working again. Hopefully this helps.
