Why did some of my imported products come in as drafts instead of live?

Your plan sets how many products can be active at once. When an import would go past that number, the extra rows are not lost. They are saved as Draft, and the import result explains that your plan allows a set number of active products.

To publish them, either:

• unpublish products you no longer sell, then set the drafts live, or
• upgrade your plan to raise the active-product limit.

Everything else in those draft products (prices, images, details) is already saved.
