How To Separate User Base On Different Storefronts?

For MV-Ultimate: How to separate userbase for different storefront?

As per Documentation:

https://docs.cs-cart.com/latest/user_guide/stores/customer_accounts.html

But I couldn't find Setting->Stores

Interesting. Please contact support for official answer. Looks like a bug

Seems to be working as designed ... the documentation linked topic from first post states

"This article applies only to CS-Cart Ultimate. In Multi-Vendor Ultimate, the customer base is always shared by all storefronts."
