The Support screen in the sidebar (right before Settings) is the channel for opening and following tickets with your provider’s team — the company that operates the Platform. It’s different from your own agency’s internal tickets about your customers (Manual 20 · Tickets, and their summary from a contact’s record in Manual 27 · Marketing and contacts): here you’re not talking to your own team about a customer, you’re talking directly to the platform.
Note — Only administrators see it with content
The Editor and Read-only (viewer) roles see the Support screen, but with the notice “Administrators only” (“Ask an administrator of your account to open or view support tickets.”) instead of content. Only the Admin role can create, see and reply to support tickets.
The table shows, for each ticket: the Subject, its Status (section 3), its Priority, who on your provider’s team it’s Assigned to (“Platform Admin”, or “Unassigned” while nobody has taken it), and the Updated date.
