This is the Collaboration team update for 1/28.
We are in early stages of improving the user experience for enabling and disabling Flow boards.
We enabled Flow on two pages on Portuguese Wikipedia, and are preparing to finish enabling Flow for the Co-op (https://en.wikipedia.org/wiki/Wikipedia:Co-op).
We fixed an urgent issue caused by moving a regular page into Flow's topic namespace (both preventing the issue in the future and treating the symptoms this time).
