Truth Soul Armor review for Amazon by Codisto

I've had this app for going on 4 months now. It seems there is a disconnect between Amazon and Codisto. None of my products are coming through with parent/child variations. The t-shirts I am selling only have color and size variants, which should be simple. Codisto's response was for me to talk through customer service with Amazon, which completely defeats the purpose of having the app. If I wanted to go direct to Amazon, I would have. Seriously frustrating to waste $40/month for 4 months now with Amazon Seller Account only to have none of my products be able to be displayed correctly. Really friendly customer service, but not working quick enough for me. Finally decided to cut my losses and try a different sales channel/appl.
