Hi,
Thanks for using our plugin and reaching out to us.
This, most likely, is being caused by you having lots of attributes in WooCommerce. All of those attributes will be shown in the drop-downs on the field mapping page. When there are too many the website might run into a server configuration limitation when populating the drop-downs.
You can probably solve the issue by enabling this general plugin setting:

Can you give it a try and see if that solves the issue at hand for you?
Oh my goodness – now that is impressive response time!!
And yes – that did the trick – Can I ask what that does specifically? Am I losing some setting?
You are now only getting the attributes in the drop-downs needed for your feed + the ones you created yourselves in WooCommerce that contains data.
Assuming the issue at hand has been resolved and our support is no longer required I am going to close this topic for housekeeping reasons now.
Please do not hesitate to reach out to us whenever you need our help again.
