Customers aren’t imported

Hello,

I’m using the “Advanced” plan on Shopify. I followed the documentation exactly. Token key is correct. I was able to import products and orders without any issues. However, I am unable to import more than 85,000 customers into my WooCommerce site. I receive a notification that the customers were imported successfully, but no customers were actually imported.

I have read that many people experience issues with importing customers. What could be the reason for this?

Thanks!
