Thank you very much for the details, I was able to figure out the issue. It is related to a known bug, which is causing me headaches for some time now. It's related to the latest plugin version and some of the WooCommerce versions. It's caused by a mistakenly active code part to filter inactive products, which I was testing only, but forgot to remove it before the release.
I've corrected the issue in the plugin files, you don't have to worry about it anymore. If you are interested, here is the description of the exact fix I did.
Now it should hopefully return the products as expected.Best,
