If I go to a specific dashboard URL when not logged in, e.g. bookmark for a CF domain, or using a browser’s site search feature to jump to a domain search, Cloudflare will prompt for login, but will then forget the original URL you asked to go to and just dump you at the main dashboard screen.
Can it please redirect you to where you were trying to go after the login as been authenticated?
e.g. I bookmark the URL https://dash.cloudflare.com/abc123/example.com/dns/records so that I can quickly get to the DNS screen for my main domain. But when I click this bookmark, it asks me to log in and then just send me to https://dash.cloudflare.com/
