As of the last update 4.14.1 abandoned carts and completed purchases are tracking as separate direct entry visitors, throwing off the campaigns and visitor counts.
I have trialled a fresh install on the existing website with a new tracking code. Also tried a new woocommerce install with both new and old Matomo install.
The issue appears to continue.
It is also impacting the conversions export as the conversion isn’t showing as a purchase from google / bing.
