title: A App deep link to B App show Safari cannot open the page because the address is invalid site
body: <p>I have a question about deep link.<br></p>
  <p>And I also used URL schemes to open B App like this.<br>
  <a href="https://i.stack.imgur.com/ZlmG1.pngl" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZlmG1.pngl" alt="enter image description here" /></a></p>
  <p>But If when my B App doesn't install in my phone, it will show this message.<br></p>
  <p><code>openInbox://xxxxxxxxx</code></p>
  <p><code>Safari cannot open the page because the address is invalid site</code> <br></p>
  <p>How to fix this issue?<br></p>
  <p>Or how to use universal link to fix this issue?<br></p>
