Hi Rob!
Thanks for getting in touch with us! I’d be happy to help you with that.
By default, Event Tickets Plus will create the WooCommerce product with the “Catalog Visibility” set to hidden. This could be the reason why ticket products are not showing up in any of your shop pages. You can of course change this setting by editing the product from the WooCommerce edit product admin page, specifically inside the Publish metabox.
Please try changing the catalog visibility and see if it makes any difference. Let us know about it.
Best,
Victor
