Yes. After two days of searching for a problem, I found this solution. Everything works fine now. Have you tried to configure WooCommerce Integration settings from business.facebook?
Go to business.facebook.com > all tools > business applications.
Uninstall WooCommerce Integration and add it again. Let me know if it helped.
