UPDATE 28-10-2022: Do not enable the events. Klaviyo has made changes to its API and therefore these events will not work and can produce errors. We are working on this and once the new version is released you will be notified via email.

These features are only available from module version 2.3.0

OpenCart 2.2.0.0 and lower versions are not updated with these features. Only OpenCart 2.3.0.2 and all higher versions have these features.
