The AppMachine platform offers two types of updates; Store Updates and Content Updates. 

Content Updates vs Store Updates

When you update your app, AppMachine will submit either a Content Update or a Store Update. Which update is submitted depends on the changes that you have made to the app since its last update. 

Content Updates: 

• Include the most basic updates to your app's design and content.
• Usually available within 5-10 minutes.

Store Updates:

• Required for changes to the app icon, the store screenshots or to the store information.
• Required if the app now includes a block that was not available at the time of the last store update.
• Required to fix bugs in the code.
• Store Updates take about 24 hours to process for Android apps and 5-10 business days for iOS apps.
