This module is being included in the next release of Twitch Wholesale PRO Public/Commercial for ZC 1.56c as the Twitch Bridge Matrix now handles product and category level relationships with customer groups using the new wsPRO Manager in Admin.

Release is pending imminently for Zen Cart 1.56c and will be next on the list for development into ZC 1.57c when funding/donations afford it.

Thanks for your support!
