How to understand the output of optimisation tools
Our apps are optimized to minimise the app loading times by making use of the appropriate caching and compressing mechanisms in order to deliver the best user experience possible.
We are aware that optimization tools that measure the performance and loading times of a store are often used by merchants and when our apps appear in the results this is usually a motive of concern. That’s the reason why in this article we want to explain in detail about those particular messages.
As an example, please find below some common messages that you might receive from an optimization tool related to our apps:
