No push notification Viber, Telegram, other, AND no "Security" app (like here: https://austinmarton.wordpress.com/2017/01/08/meizu-flyme-notifications-fix/)!
Meizu C9
Android Version 8.1


Where I can download this "Security" umbrella application?
Or what other method to make work push notification?


Thanks
