title: Why are my MapView's zoom limits not working?
body: <p>I am trying to restrict the max zoom "out" for an application I am making. The issue is that, even though I set pretty limited zoom restrictions, the user can still zoom in and out as far as they want. I'm relatively new to Expo applications, so it might be something I just don't understand about the <code>react-native-maps</code> library.</p>
  
  <p>Here is how my map's <code>render()</code> method looks:</p>
  
  <pre><code>render() {
  
          return (
              &lt;MapView
                  style={styles.mapStyle}
                  region={this.state.region}
                  provider="google"
                  zoomEnabled={false}
                  minZoomLevel={18}
                  maxZoomLevel={20}
                  showsMyLocationButton={true}
                  showsUserLocation={true}
              /&gt;
          )
      }
  </code></pre>
  
  <p>I have logic in place to center the map on the user's location (not shown - that's handled in <code>componentDidMount()</code>), but the zoom restrictions here don't seem to have an effect beyond the initial rendering of the map. Once the user zooms out, the sky is the limit - they can zoom out to see the whole world, if they wanted to. That's not very useful for my app, so I'd like to get these restrictions working (or at least a better understanding of how this works). Thanks in advance!</p>
