Problems on configurable product sync on Magento 2

Hey Team,

We are setting up our first Klaviyo account which should be integrated to our Magento 2 website. Most of tasks are completed smoothly, but we have problems with products Sync:

1. Some configurable products can’t be uploaded to Klaviyo by the integration extension.
2. The variant product under configurable products isn’t synced the price with our Magento 2 website (Simple product is good.)

If you can have a check on these problems it will be really appreciated.

Kind Regards,
