iOS9 Email Push Still Not Working [closed]

There seems to be a general iphone issue with mail.app not pushing correctly atm. I've tried every trick I could find online, but to no avail.

What I've done so far:

• Reset network connections. Did nothing.
• I've deleted and re-set up my email accounts in mail.app. Did nothing.
• All of the notification settings are correct, including push, and background update is on.
• Re-entered email account passwords, nothing.
• Both mail.app and gmail.app refuse to actually push mail and notify me unless I manually force a refresh. Even fetch doesn't work.

I'm not sure why this happened all of the sudden. I updated to 9.1 couple weeks ago, but the issue started a couple days ago. It's terrible for work, I'll get emails 2-3 hrs later when I randomly check.

Any help is appreciated.

this worked for me

Go to Settings >> Notifications. Scroll down and find Mail section. Tap on it. Select your mail app. For example, I am using Exchange. Turn on “Show in Notification Center” and “Show on Lock Screen”.
