In general, I can’t answer questions about how CWA works (or doesn't work). Sorry.
I just make the web browser (the CrewWeb app), so asking me a question about CWA is kinda like asking Apple or Microsoft.
User guides for CWA are available on SWALife. Log in to SWALife and search for ‘CWA user guide’. Make sure you get the one for Flight Ops or Inflight, as appropriate.
