DRFでManyToManyFieldの更新ができない

Question

DRFで下記Newsモデルへの更新が動作しません。
作成は正常に動きます。

class News (models.Model):
    id = models.AutoField(primary_key=True)
    title = models.CharField(max_length=20)
    text = models.TextField()
    address = models.ManyToManyField(Group, blank=True)

class Group(models.Model):
    id = models.AutoField(primary_key=True)
    group_name = models.CharField(max_length=20)

class NewsSerializerViewSet(viewsets.ModelViewSet):
    queryset = News.objects.all() 
    serializer_class = NewsSerializer 

class NewsSerializer(serializers.ModelSerializer):
    class Meta:
        model = News
        fields = '__all__'
