I may have figured out my issue. The default search boxes on my site (on top right of each page in the header) and at the bottom of the search results page are WordPress – not WooCommerce Product Search widgets. If I add the WC Product search widget to the sidebar, it is able to find products by SKU. So, not an issue with the plugin… maybe just a problem with teh way 2.2.4 works on my site? I guess I’ll be working to find a way to switch regular search boxes to WC Product searches now.
Thanks for your time and plugin!
