Niko Access Control - Digital - My Android 10 Huawei does not always receive the call.

Huawei has its own setting that determines its apps' startup behaviour.

By default, this is set so that apps that have been inactive for some time cannot start up automatically.
Due to this setting, the external unit's push notification will not appear on the smartphone.

Through Settings => App startup behaviour, you can give the Niko app permission:

• To start up in the background when the device is started up.
• To be started up from another app.
• To be able to consume data and energy in the background at all times.
