Hi there,
I recently purchased Amelia. On the checkout process in woocommerce the recurring appointments don't appear. I just checked and discovered an error in the following file:
ameliabookingsrcInfrastructureWPIntegrationsWooCommerceWooCommerceService.php

Line: 1343

$recurringInfo = $recurringInfo ? array_column($recurringInfo, 1) : null;

This line should be like this in order to show the recurring Appointments correctly:

$recurringInfo = $recurringInfo ? array_column($recurringInfo, 0) : null;

Hope it helps to correct the issue in next update.
Best Regards
