@Johann,
The message does display, but seems to only display once and doesn’t prevent you from viewing the website. Simply ‘x’ out of the message and continue to browse.
Thanks for the reply.
Sorry, but this not the solution.
Chrome, Chromium, Vivaldi, Yandex and Slimjet show not this adblock warning.
Then it should be Brave too.
The above is an image of me visiting the site in Chrome with the uBlock Origin ad-blocker extension installed. Note the same warning is displayed. This is because the site detected the ad-blocker. With Brave, the ad-blocker (Shields) comes built in, which is why you saw this warning.
