I couldn’t get this Gooten plugin to work either, and just transferred an entire workflow to Printful.
Gooten’s advice is to downgrade Woo Commerce to many versions ago 3.9 (somehow save your database), then connect, then re-upgrade WooCommerce, then reconnect your data… Um, no thanks. I hate it when a solution is likely to cause devastating problems and more time if you mess it up.
The support just isn’t there for this. Connecting was incredibly smooth with Printful. It is the best of the three right now with Woo. I also have connected to Printify, but still exploring if I can use them both or not.
