Hubs may not be visible if you haven't been assigned to them. To gain visibility, you need to be added through one of these methods:
Option 1 (best for multiple users + ticket auto-assignment):
Operations > Hubs > Manage (select a hub) → Assign Teams or Users for visibility, auto-assignment, and notifications > Save Changes
OROption 2 (for individual users):
Settings > Users → Select a user → Hubs Access > Edit → Select hubs → Save
Optional: Tick “Add user to new hubs” for automatic future access.
