I have to correct me. Elementor and Spreadplugin work in general and it is supported, but not in every special case.
What I did:
* Create a new Page
* Click Edit with Elementor
* Drag & Drop Elementor-Shortcode
element to the desired area
* Insert [spreadplugin]
at Insert your Shortcode
text field
* Save it and go back to Spreadplugin Settings
* Click Rebuild Cache
at Spreadplugin Settings
This worked for me, so if you still want to use Spreadplugin, you may separate your Woocommerce product archive page from Spreadplugin articles page.
I understand you want to combine both, woocommerce and spreadplugin in an Elementor Template, but this is not working at the moment. A working alternative could be to have a products page with woocommerce and a separate “merchandise” page with Spreadplugin.
What do you think?
