title: React - Error while updating from 17.0.1 to 17.0.2
body: <p>I am getting the following error while updating from React 17.0.1 to 17.0.2.
  It's not entirely clear to me why the dependencies are causing problems.
  I'm using npm v 7.4.</p>
  <p>It seems that some dependencies are incompatible with react 17. Do I understand correctly?
  But npm shows e. g.</p>
  <pre><code>npm ERR!   peer react-dom@&quot;^15.0.0 || ^16.0.0 || ^17.0.0&quot; from react-calendly@2.0.0
  npm ERR!   node_modules/react-calendly
  </code></pre>
  <p>If I think correct, React 17 should work.</p>
  <p>Could someone explain the problem to me briefly? Is there a solution for this?</p>
  <p>Error:</p>
  <pre><code>npm install --save react@17.0.2

  <p>I don't understand, why 17.0.0 should be working, but 17.0.2 not.</p>
  <p>Thanks for your help.</p>
