Hi Everyone,
Thank you for sharing your feedback on this topic. We wanted to share what the reason this issue was occurring with Anyuta3D in case anyone else was seeing this on their end. First, whenever a model is rejected from a customer order for your product, the product settings are automatically reset so you have the option to upload a new model which you can link to the product.
However, please keep in mind that when you link a new model to the product, you also need to make sure the model/material option is also visible for the product itself. You can see this on the "Pricing & Model Files" section of the product edit page as "Eye" icons:
Simply select the icon and you should see the model file is visible to the product at that point. From there, simply save changes(along with making the product visible to customers) and you should be able to sell the models again to customers.
I hope this helps!
All the best,
