 You can only call `.load` on page load, or reload (refresh). If you modify the `.load` method between page loads, it doesn't have any effect until the page is reloaded.
 
+Note that if you add `All: false` to your Load call, you must also add `Segment.io: true` to the integrations object to pass data to enabled destinations.

 For example:
 
 ```js
-analytics.load('writekey', { integrations: { All: false, 'Google Analytics': true, 'Segment.io': true } })
