&gt;They are actually rarely on the same release schedule industry wide. But this is actually insane since back-end code is a lot faster to fix than front-end code, because you only need to change stuff on the server side instead of going through the app review process of App Store &amp; Google Play. 
  
 There's ways to live patch mobile app and skip the review process.

Yeah, by changing server-side APIs like they said. Its not actually changing the code of the app though.
