We are using this extension. We have 12 websites and we set Customer Sharing as "Global". We also have option "Create user if not exist" set to "Yes"
Issue is we can not login with same customer on another website. It show me an error:
The auto-provisioning process failed: Customer email already exist

Can you let me know what we need to do to make it works? We need to set Customer Sharing as "Global"

Thank you
