Shopify synchronization

Installed erpnext_shopify v. 2.0.26 from

I have enabled the shopify app and defined it as private, entered API keys, etc.

While trying to sync shopify with ERPNext nothing is transfered neither direction.
Shopify log shows:

Updated 0 customer(s), 0 item(s), 0 order(s)

Is there a bug with current shopify connector?

The erpnext_shopify app is deprecated. Shopify connector is now built into ERPNext.
