Ads wont show on windows 10 desktop

I am having an issue with ads not showing on my brave browser. I have ensured that Brave has permission to show ads in my windows 10 operating system. I have also used a browser notification tester to ensure that notifications work. I have un & re installed the browser on my desktop. Can someone from support please help me?

can anyone help? ive sent an email to the brave team and no response
