Product Images Don’t Publish to Store

I’m preparing to go live with my new site, and the store connection worked . . . except for 1) product images don’t show up (just the placeholder); and 2) the product is listed as “Out of Stock.” I have dis/reconnected multiple times, deleted and recreated the product, and even tried with more than one product option. Same results: everything but the product image shows up, and it is “Out of Stock.”

I’m using WordPress 5.1 with WooCommerce 3.5.6

I’ll keep tabs on this support forum, but it looks like people aren’t getting much help here. In the meantime, I’ll look at other dropshipping options.
