After a major update to the plugin, and quite an extensive back and forth with the team at WP Funnels, it works beautifully and amazingly well on my WordPress site.
I wanted to stress the fact that the team at WP Funnels is very responsive, they respond to my emails within the day and they do what they promise.
If you want an amazing drag and drop funnel editor that enables you to upsell, downsell and cross-sell items, THIS is what you need.
I used to reply on OneClick Upsell but it didn't have the option to down-sell, and not even clone the pages and funnels to save time doing multiple funnels.
WP Funnels meets all expectations and ticks all the boxes, and one of the best parts is that you are able to work with Elementor and create the upsell and downsell pages as you want.
Excellent work, well done!
