I’d like to add my voice to the frustration with these messages. I visit the site dashboard as directed, and I never know what there I am supposed to be seeing. I am the most active admin, as the Staff Action Logs confirm for me when I visit there, and it seems like nothing unusual has happened.
Can the message include the advice and recommendations? To me, the current message might as well say, “There’s something important for you, but we won’t tell you what it is. Go to a complex noisy page and see if you can figure it out.”
