Can't connected avitab with navigraph

When I try to connect avitab to navigraph via the navigraph account link, I always get this empty window after logging into my account.
No possibility to approve anything or any interaction
The window remains empty? What am I doing wrong?
Chrome is my standard browser

Thanks for your support?

Hello! Welcome to our forum.

What happens if you copy the full URL from the address bar (the one beginning with identity.api.navigraph.com) and paste it into another browser?

I suspect you are using a browser extension that is causing trouble.

Alternatively, you can copy the URL and paste it into the address bar of a new Incognito window (which can be opened using Ctrl + Shift + N in Chrome).

Kind Regards,
Malte
