Is the performance issue in Composer (when you use platform.appgyver.com) or in Preview?

From your question I assume you are experiencing performance issues in Preview. My recommendations would be:

  1. Only fetch the data required (don’t fetch all but filter whenever you can)
  2. Don’t repeatedly fetch the data (no loops whenever possible)
  3. Store the data you require in an app variable and access that all over the app instead of setting up multiple data variables to use the data from
