The support we have received from Store Apps has been outstanding.
We faced an issue with creating a huge amount of variations using their “Bulk Variations Manager” plugin. They offered us to look through our administrations settings and they send several detailed instructions with screen shots etc. Together we solved the issue and we couldn’t have asked for a better support. The “Bulk Variations Manager” plugin is by the way, a fantastic addition to WooCommerce and we can easily create thousands of variations during few minutes
