I have visited multiple sites that bypass Brave shields and identify that I have an adblocker present.
Also many websites open pop up tabs which should technically be stopped by the brave websites.
For example: https://moviesjoy.to/
I just pulled it up on my Windows 10 running Version 1.41.96. When I clicked on the link they provided, which was https://moviesjoy.to/ it originally loads with no issues. However, once I clicked on the page a pop-up came.
That’s just on its home page. After clicking View Full Site it seemed to work better, but couple movies I navigated to had some pop-ups. And when clicking to play/pause, it would have a pop-up ever so often.
