Dear Russian-dima -
thank you for your quick and helpful reply.
Unfortunately I am not using Wix Stores. Because our system in the stores (Shopkeep) only integrates with Ecwid. And in turn, I think Ecwid integrates with Wix.
Not sure if I should try first a contact through Ecwid first.
And then if not, come back to see if any of your suggestions could help me. Thanks again.
Nina
