Description

The "Enquiries" tab on the user dashboard did not display the total enquiry count next to its title, unlike the "My Listings" tab which shows its count (e.g. My Listings (12)).

Solution

The total enquiry count is now fetched using:
ATBDP()->formgent->get_kpis()

The count is appended to the tab title using the same sprintf pattern, resulting in:
Enquiries (5)
