Hello everyone. I'm new to Amazon Merch and although I find it pretty easy to upload a design for a shirt, publishing the product is a whole different story. I've filled out all the necessary descriptions/details etc., but when I try and publish or save draft I keep getting a system error. I came back the next day and still the same thing. I've tried to create a product about 15 times now. It doesn't save anything. I feel like I'm just running in circles and Amazon has provided no instructions to help. There's only instructions on artwork. Any help would be appreciated.
