I signed up, confirmed my email, opened the app and was browsing through it and was on settings tab when I got a phone call. During that call I had to look up something so I opened a new tab. After the call I went back to resend's UI to watch it blink and all of the sudden I'm on the dashboard again.
So I tested it, I went to the settings page again, switch to a different tab and then back to Resend again just to watch it switch back.
There is absolutely ZERO reason for this functionality. It is not a better UX, it's an annoying UX you do not know what I am doing or where I want to be on your website.
