Skills moves onto the Configuration page
Skills was the last part of the catalogue with its own sidebar entry. Services, products and industries had already moved onto the Configuration page, so maintaining the catalogue meant going to two different places depending on which part of it you needed.
What you can do now
Open Configuration and pick the Skills tab. The list, the search and service filter, and creating, editing and deleting a skill all work exactly as they did — they sit beside Services, Products and Industries instead of on their own page.
The Skills entry has gone from the sidebar for admins, customer success managers and service delivery managers, since the Configuration entry now leads there.
Links you already have keep working. An old skills link — a bookmark, or one in a notification or a document — takes you to the matching place on the new tab, and a bookmarked filtered list arrives still filtered.
Who can see the tab has not changed: the people who could open the skills catalogue before can open it now, and editing a skill still takes the same permission it always did.
