Branch does not send events to Amplitude

Question

I have implemented iOS and Android SDK, now I am testing my app configuration in test environment. While everything works fine with iOS, I noticed that with Android, events are not passed to Amplitude. I expect to see the [Branch] OPEN event in Amplitude. I registered Amplitude API Key in Branch settings and its status is enabled. In the Liveview section I see my Android events. What am I doing wrong? Please help me understand. Branch App ID: 705693665045009364

Build.Gradle:

buildTypes {
    release {
        ...
        manifestPlaceholders = [
                deeplinkDefaultDomain   : "faceter.app.link",
                deeplinkAlternateDomain : "faceter-alternate.app.link",
                isBranchSdkInTestMode   : false
        ]
    }
    beta {
        ...
        initWith release
        debuggable true
        applicationIdSuffix ".beta"
        manifestPlaceholders = [
                deeplinkDefaultDomain  : "faceter.test-app.link",
                deeplinkAlternateDomain: "faceter-alternate.test-app.link",
                isBranchSdkInTestMode  : true
        ]
    }
}
