Ensure you've updated the store settings that will allow you to change the print file before sending the order to production.
1. Access Stores from the dashboard, click on the three dots from the right side, select Settings, then scroll down to When you want orders sent to production?
2. Select Manually to create orders as drafts, which will only go into production after you manually approve them;
Select the Delayed option to set up a custom time, after which your order will automatically go into production, e.g., 60 minutes.
3. Navigate to your dashboard, open the Orders tab, and click on the order number to access its details.
4. Click the Upload new file button.
Note: The specifications of the new print file must be the same as the old one.
5. Once the file is updated, click Accept Order.
Note: The same process applies when you want to create new artwork with the image provided by your customer.
