Another side effect of not having a Back button usable in MOS-F - I had written a reply and some suggestions to the MOS Communities discussion about the new Health Checks.
The session hung.
In a normal browser environment, I would have hit Back, copied my text to a safe place (Notepad), and tried again (perhaps later knowing that Communities is about to undergo some shutdowns this weekend).
In this environment, the feedback is lost forever.
Perhaps that was the intent ...
