title: Git branch is not updated
body: <p>I am working on my app so basically I created several branches:</p>
  
  <pre><code>feature/add-contact
  feature/edit-contact
  feature/show-contact
  feature/delete-contact
  </code></pre>
  
  <p>After working on the <code>edit-contact</code> and push my files on that branch usually I am getting this on my repository:</p>
  
  <p><a href="https://i.stack.imgur.com/lQggV.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/lQggV.jpg" alt="enter image description here"></a></p>
  
  <p>And then after clicking the <code>compare and pull request</code> button and then merge it to master, I will checkout to my master branch and will <code>git pull</code> to get the latest updates on master branch.</p>
  
  <p>After working on several feature until finally came to <code>feature/delete-contact</code> and finish, I decided to go back to <code>feature/edit-contact</code> but when I open it, all the codes are not updated even using <code>git pull</code>. </p>
  
  <p>I also tried to make changes and try to do some <code>git push</code> on the changes I've made on this branch (feature/edit-branch) but I am no longer seeing the <code>compare and pull request</code> button that I am seeing above.</p>
  
  <ol>
  <li><p>How do I make sure that each branch that I am passing through get the latest updates on my codes even when I go back to the previous branch I am working with?</p></li>
  <li><p>How do I make sure that I'll get the same pull request again after I push on a previously worked branch?</p></li>
  </ol>
  
  <p>Please help!</p>
