eBay listing error - The tags material is/are disabled as variant

The "the tags material is/are disabled as variant" error is returned by eBay when you have "material" as one of your variation options.

This is because eBay no longer accepts material as an option for products. Resolve this by changing the option of the product to a different value (for instance "product material"), then save and publish your listing again.
