The navigation macro does not work correctly. It renders for only a second on the page and then disappears. The same behavior occurs on the page editor.
This is a already known and fixed bug:
Version 1.1.1 of Subspace cloud is deployed and contains this bug fix.
However, users might still experience the behavior described above.
You should clear your browser’s cache re-open your page. Then, the navigation macro will be displayed correctly.
