Promise doesn't work with alert/Alert.alert

`[somePromise].then(resolve => {
        alert('Good');
    }).catch(reject => {
        alert('Bad');
    }).finally(done => {
        this.setState({
            isLoading: false
        });
    });`

setState in finally doesn't work with alert message. Without alert all works correctly.
