React native release bug
<p>I faced with a problem which I can't solve.
My application works fine in debug mode, but when I build it under release and install on my device I see a bug. I've created a difficult component which I use in application and which appears using animation and this component is not shown. 
Are there any practice to solve release problems? 
How can I debug this case? 
I'm new in mobile development. </p>
