title: Error updating Custom Teams App - ID in manifest doesn't match installed
body: <p>I have created a 'Hello World' Teams app following the Microsoft getting started guide. This seemed to work as expected and I was able to add the application to my app catalog in the Teams client.</p>
  <p>However, I am having problems updating the application without deleting and re-adding it.</p>
  <p>For example:</p>
  <ol>
  <li>Go to Teams App Studio -&gt; Manifest Editor</li>
  <li>Select the Hello World app</li>
  <li>Change only the version number (e.g. 1.0.0 to 1.0.1)</li>
  <li>Go to Test and Distribute and download the package.</li>
  <li>Go to Apps and click the '...' button next to the installed Hello World 1.0.0 application.</li>
  <li>Select Update and choose the package zip downloaded in step 4.</li>
  </ol>
  <p>At this point, I get an error: The id in the manifest doesn't match with the app being updated.</p>
  <p>Comparing the manifest.json file between the 1.0.0 and 1.0.1 app, the only thing that is different is the &quot;version&quot; field. Everything else, especially the &quot;id&quot; value is identical. I get the same problem when I manually alter the application version in the manifest.json and attempt to update the app. This happens with any custom app I've uploaded.</p>
  <p>Any idea why I am not able to update an installed application? Am I missing something and these steps are just not valid?</p>
