    Resolution Note:

    Seems that this is only reproducible on a Xiaomi device:

    Seems that Huawei (including Honor) and Xiaomi utilize aggresive batter saver techniques which restrict app background activities unless the app has been whitelisted by the user in device settings. This means that any scheduled notifications will not be delivered if the app is closed or not running in the bacgkround. We are not aware of any way to workaround this behaviour besides encouraging the user to whitelist your app.
