I found an issue with the data integration of EcomProducts related with products XML that worked in previous versions (until 8.8.1.13) and with the lasted version it seems to ignore the products.
You can check the problem in the screencast I’ve made:

I’ve used the same XML transformed with the same XSLT and the result XML is showed in the video.
From what I can found in the DB it seems that the EcomProvider is ignoring the products with variant id filled that are the lasted to appear in the XML.
Best,
