<p>I personally saw the crash on the user's iPad and strangely after the crash the app remained locked on the splash screen of the app even upon clicking the home button.</p>

<p>If I try to symbolicate any of the entries in my own project I get:</p>

<pre><code> atos cannot load symbols for the file 3rdparty for architecture arm64.
</code></pre>

<p>Is it a problem in my app or in the user's device I may help him to fix?</p>

<p>Thanks</p>
