Brave survey - strange behavior

I just got a Brave survey via Ads, URL https://brave.com/surveys/b2/. Survey is not loading and a strange address under “Open in Tor” is displayed. Survey was working e.g. in Edge Browser. What is the issue?

Hi @juerg_baur, what OS and Brave version are you using? It’s currently loading as expected for me on the latest Release version.

Hi Steeven, I checked the link for the survey today again and now the page is loaded.
