Ah found the issue (kind of got the hint from browser interrupted the opening of a new tab message in your screenshot 🙂 ). For some reason allowing the popup windows is causing the bug. I changed it to Block and restarted the app and viola! It works as you say. But this is not the supposed behavior right? or is it 🙂
Now I got the same message as @dino received and successfully logged in ✨
