Honor 10 notification problem

[Saujla10]

I have the Honor 10. When I get a message my phone vibrates but the notification LED doesn't flash until after I've pressed the power button to turn the screen on. If I miss the vibration I have no idea I have a message until I check my phone. I have tried installing various LED apps like the LED Blinker Pro but nothing works. I don't understand why the LED will work but only after I've checked my phone

Any help anyone can provide would be greatly appreciated

After tweaking a few settings sometimes the led notification flashes and sometimes it doesn't, all very random
