I noticed this today. Don't know when this was added or if it's been part of the app all along and I just never paid any attention. I admit I don't navigate to the Settings>General page that often and when I navigate to Settings>Accounts or any other page under Settings, I don't pay any attention to the General page as I pass by, so…
I'm wondering where the "personalized insights and summaries" are showing up other than perhaps just in general in the Reports?
