Shopify Marketplace Connect

I have to say the app does its job and the support team is there to help, however their instructions were very harmful for our business.
We asked two different times to two different support people if the application would respect the FREE LIMIT from ebay, so we could simply activate all items and let them sync.
They said yes not one, but twice. But a week later we encounter a 40€ payment and a 50€ payment from ebay. The limit was surpassed.
I believe not having the option to agree to surpass this free limit is a big hole on the implementation, and the terrible understanding of the support team was a tremendous let down for us.
i would greatly recommend not trusting their recommendations.
they also didnt take acountability from their mistake.
