"Under Sales Channels, select the sales channel you wish to integrate with Klaviyo from the dropdown. Only integrate one sales channel with Klaviyo per Shopware store. You must also configure your settings for each sales channel individually."

We are starting with Shopware and are longterm Klaviyo users with a multi-channel Magento store. The text above appears to suggest that the free extension does not support more than one sales channel - which as many Shopware installations would use multiple sales channels for different regions and languages, would seem to make this extension useless.

But then the text “configure your settings for each sales channel individually." seems to contradict this. 

Can this extension be configured to work with multiple sales channels with Shopware?

What is your experience with the extension - look at previous comments, it appears poorly supported, slow to synchronise and slow to be updated to new Shopware versions.
