Ionic iOS push notification coming through but won't work if app is closed

Hi guys,
been working on getting push notifications working in iOS and have them working on android, the issue I have is that I get the notification ok in the app however anything outside the app including the notification sound and notification in the pull down thing are not appearing.

Could someone point me in the right direction as to what this could be, it looks to me like a permission thing with the certificates etc… however I have followed the instructions and am out of ideas.

Thanks guys

What service are you using to send push notifications?
Which library are you using to handle push notifications in you app?

Bit late in responding however after days of mucking about with it a multitude of things were wrong, mainly getting the certificates correct which I don’t think the docs go into enough detail on how to get them set up in xcode etc…

Thanks for the reply though.
