Hi,
So i just tried some trouble shooting and it seems like the plugin “WooCommerce Multilingual” is the one that is causing the issue. When the plugin is deactivated the “Download CSV” button sends an email with a CSV link with a file called “wc-products-report-export-16288605243266”
When “WooCommerce Multilingual” is activated the “Download CSV” button downloads the file called “varer_2021-08-13_page-wc-admin_path–analytics-products” directly in the browser.
