"Keep it" makes the results disappear

Using Copilot with Outlook (both the desktop and the web app), when I give it a prompt, it creates some good content, but when I click "Keep it" the content disappears.  I have tried this several times.  I closed the apps and restarted with the same results.  I restarted the computer and still the same results; clicking "Keep it" does not.  Any suggestions?  Please!
