Thank you, but if you look at the dashboard, where I created the template in accordance with tutorial, you will see that it is a different name to that being shown in Toolset > Woocommerce blocks for the woocommerce views.
Selecting Woocommerce Views as you advise makes it even worse
I found that the custom template was no longer bound to the products. I clicked apply to all and it is now working. Not sure why updating plugin would change that, but at least it's now working. Thanks
