Hey @yassine I have a similiar issue and definitely watched your video upon setting up.
So sales are coming through on paypal,
contacts are loaded into clickfunnels fine... however no payment or product/s are attributed to them.
I went ahead and double checked all of my products to make sure the ID's match as well as the funnel URLs.
Any suggestions from there? Otherwise, this looks promising for sure
If it provides any insight, I have 5 products on the front end order page. 1 is a bump.
and definitely followed what you said to do throughout the video for those as well.
