That's strange. I got the update for Edge separately from the 2004 update some 3 weeks ago. Works really well. A lot like google Chrome and without the google connection.2004 install went fine however Edge still hasn't updated. No big deal; I don't use Edge but do wonder why it hasn't updated.
As for the 2004 update, there's a message that "my device isn't quite ready yet".
I looked this up and it seems to mean: "we still have to iron out some bugs in the 2004 that might affect your system"
