Social Listening Upgrades, Meetings & Drive Improvements

New Features

• Social Listening — Adds per-user read/unread state to mention cards, an "Only unread" filter, bulk mark-as-read, and saveable custom filter presets with shareable URLs.
• Meeting Attachments — Files and links can now be uploaded and managed directly within a meeting.
• Survey Email Preview — View the exact personalized email sent to each survey recipient from the responses page.
• Health Metrics Tooltip — Registration Revenue now shows an info tooltip clarifying how revenue figures are calculated.
• Intercom & Navigation — Support links in LFX Drive and v1 pages now open Intercom; the Marketing Metrics page has been removed.

Bug Fixes

• Social Listening Speed — Resolves an up-to-60-second blank-page delay by switching to WebSocket connections; the page now loads in under 5 seconds.
• Intercom Session on Logout — Ensures the Intercom session is properly closed when signing out of LFX Drive.
• Mailing List Errors — Shows the specific failure reason when adding a mailing list member fails, replacing a generic error message.
• Committee Updates — Removes the "Counsel" role option, fixes incomplete loading of large committee lists, and hides the legacy meeting attachment menu item.
• Meeting Recurrence — Fixes custom recurrence dialog dismiss and monthly weekday save issues.
