This is a very minor detail but it's hugely annoying. I came from an iPhone 5 running on iOS9. When I get an email that I know is junk (that is a notification), I can just press 'delete' and that will delete the mail from my inbox. No red badge alert. The problem is now that I have an iPhone X. When I 3D touch the mail notification, I have two options. 'Delete' and 'Mark as read.' It doesn't matter which I select, it will not reflect it in the Mail App. The notification will go from the notifications bar, but the mail will remain with a red badge alert, and be unread. The only way to delete it is if I open up the email and then delete it. What I can't understand is why both the option delete and mark as read is present, but it doesn't do anything! I want to know if anyone else is having this problem, and whether there is a fix for it. I can't work out if it is my email server or the app/iOS itself, but I have tried with other email accounts and the same issue persists. Many thanks.
