Please exercise caution when using any of Mailchimp's new features. Some of them are so new that they have not been integrated into Mailchimp's API. This can result in little or no data being available when performing any of your Chimpegration processes.
At present, we have noticed limitations with Advanced Segmentations, SMS campaigns and Customer Journeys
Standard Segmentation and Classic Automations still behave as normal with Mailchimp's API and as such can be used by Chimpegration.
As soon as Mailchimp integrate their new features into their API, we at Zeidman Developer will make them available within Chimpegration.
