Problem with Huawei P10

I've had a miband 2 for long time and at first everything was fine, then to get more feature i uninstalled MiFit and got Notify after a while i moved bacj to MiFit but app notification was no longer working so i stopped using it (since it wasn't very useful for me). Now i just bought a mibad 4 and i still have the same problem (phone calls notification works fine), does anyone know how to fix it? M9appsy phone is a Huawei P10 with Android 9. Thanks in advanc
