[Q] No push notification on data screen off topic

Hello everyone,

I have my Huawei Ascend Mate 7 for two months now and I noticed a strange problem : Push notifications of certain apps not working. Only on data while screen is off. Apps like Whatsapp for exemple. If I turn on the screen on or if I press a button (even just "volume up") the notification arrives. Whatsapp is set as "authorized" in the notifications manager. The app is also checked in "protected apps". I use "Normal" mode as Energy profile. Data is set to "always on" in Network menu.
Gmail seems to work correctly on data. Everything works absolutely fine on Wi-Fi.

It seems like certain push notifications "fall aslepp" immediately after the screen has turned off and arrive if I wake the phone up by simply press a button.

Any ideas on what is going on ? It's a very annoying problem. I had an HTC One M8 before and everything worked fine...

Thanks in advance for your help. I precise that I am french, I do my best in English !
