Hi,

 

I wanted to understand if its absolutely necessary to load adobe launch script asynchronously or we can defer it.

What would be the impact if we defer the script.

You can make the Launch script load synchronously by removing the "async" attribute in the <script> tag. But by doing so, you lose all of the benefits of asynchronous code execution within the Launch library, e.g. all actions in a Rule will run synchronously. Make sure that that is your intended result too.

According to Andrey, you should not use the "defer" attribute in the Launch embed script tag. See here: https://experienceleaguecommunities.adobe.com/t5/adobe-analytics-questions/adobe-launch-async-javasc...
