title: React Native Maps onRegionChangeComplete Fails to Fire on Second Drawing
body: <p>In my React Native app, I've built a city search using React Native Maps and the Google Places API. </p>
  
  <p>I use a city's latitude and longitude I get from Google to render the map.</p>
  
  <p>The <code>onRegionChangeComplete</code> callback fires the first time I draw the map for a city. However, if I search a second city and then the first city a second time, <code>onRegionChangeComplete</code> fails to fire for the second visit to the first city.</p>
  
  <p>It's as though the tiles for that city are cached and therefore the map does not fire a change.</p>
  
  <p>This seems like a bug in React Native maps, but I thought to post here. Perhaps I'm doing something wrong.</p>
  
  <p>For context, the reason I need that event to fire is because I populate the map with markers that fall within the map boundaries. I wait for a map change to complete before determining which markers to show.</p>
  
  <p>Currently, the map remains empty on second visit to a city because the callback I chose is not firing.</p>
