Issue after avada update - Simple product template is no longer using default WC product template?

All was working well but after the Avada update I have a major issue with a multistep product customizer.

It worked fine with Avada! It still works fine with other themes! Only Avada now has this issue.

Plugin: Advanced Product Fields Pro for WooCommerce
ICW: Advanced Product Fields add-on: layered images
Following multistep tutorial:

According to their support the reason for that is due to Avada’s single product template. For some reason, it is using a custom product template. The snippets from them only work with the default WooCommerce product template.
Since it always worked perfect it seems this was changed in latest update. Can this be reverted? Or can I solve this in a different way?

As this is a third-party issue, Avada would suggest you to contact the plugin author as the plugin author would suggest you to Avada support. You may need to hire a freelancer at some point if you want to get the issue fixed.

Well since this issue was not there before last Avada update and the issue is not with any other theme, I would hope Avada is seeing this as an unintended issue due to their update and fix it to be honest.

You can contact them and report the problem. They may provide you a solution
