Since 4 days ago all notifications from Instagram have completely stopped. Everything is still checked in settings to allow notifications. I have tried turning the notifications settings on and off, restarted the phone, left Instagram open, left Instagram closed and still nothing at all. I have to sign in Instagram to see any notifications. Nothing at all is showing up on lock screen from Instagram. It still has the notifications from 4 days ago but nothing recent has come through at all. Notifications are coming through for other apps it's only Instagram that has stopped
