Show the same data to all logged-in customers, regardless of their contact.
By default, every tab in eg2 filters rows by the logged-in customer’s contact — each customer sees only their own rows. A contact-free tab removes this filter: every row from the sheet is shown to every authenticated customer.
Contact-free tabs are useful for data that’s the same for everyone:
Contact-free tabs are still behind the OTP login — customers must authenticate to see them. The difference is that once logged in, all customers see the same content.
You do not need to set a contact (identifier) column for a contact-free tab — there’s no per-customer filtering to configure.
