Accordion Display Style Not Working

Thank you for sharing the video, this was very helpful.

We noticed in the video, you didn’t select an Add-on type.

As shown here, the type is still undefined as ‘Select type’

Please try selecting a type, either: Select, Radio, Checkbox or Text.

Hopefully this should resolve the behavior of the add-on not showing on the product page.

I select the checkbox, but no changes .. ((

Until the last update of your plugin, everything worked, please tell me what is the problem?

In our last few updates 2.1.0+, we have made changes to the plugin directory and code optimizations to support upcoming features and functionalities. If you have developed customized changes with a previous version or the theme, we’d recommend you review those code changes to our directory structure, as this could have impacted the theme or custom development support.

If the previous version did work for you, you can also revert back and continue to use the previously version. All previous releases are available, https://www.ads-software.com/plugins/product-add-ons-woocommerce/advanced/ under Previous Versions.
