From 07/19 3PM PST - 07/20 1PM PST, new t-shirts selected to publish live on Amazon were published as sample t-shirts. This means that the t-shirts are non-discoverable (you cannot search for them on Amazon). Even if you selected the button to "Sell on Amazon" when submitting your t-shirt, the t-shirt was only published as a sample due to this error.
If your t-shirt was affected, you can publish it live on Amazon from the "Manage" tab by selecting to "Sell on Amazon." Once you select to sell on Amazon, your t-shirt will go into a "processing" state where it will complete publishing steps to be searchable on Amazon.
This issue is now fixed for all t-shirts moving forward. If you want to share feedback or follow up questions about this issue, please comment below.
