User in 2883635-zen is complaining about the Mark this order as complete and notify the customer checkbox showing now when buying a label:

They say this goes against their workflow and creates a lot of confusion with their customers if they forget to uncheck it.

I'm asking them for more details about what their workflow is to understand why this is a problem.

In the meantime, how complicated it would be to add an option in WooCommerce Services settings to leave this box unchecked by default?
