title: Expo publishing just hangs
body: <p>When I <code>expo publish</code> all I ever get is:</p>
  <pre><code>› Expo SDK: 44.0.0
  › Release channel: default
  › Workflow: Managed
  
  Building optimized bundles and generating sourcemaps...
  Starting Metro Bundler
  iOS Bundling JavaScript [====                                                            ] 6%
  </code></pre>
  <p>and it stays there forever. I've tried clearing all caches, deleting <code>.expo</code> and <code>node_modules</code> and still get the same result. I get the same result in CI (GitHub Actions) with a fresh container.</p>
  <p>Does Expo publishing just occasionally go for periods when it does't work at all (because of backend issues)?</p>
