I got this advertisement pop up to my laptop from Brave

I am using Brave Dev (Version 0.60.15 Chromium: 72.0.3626.53 (Official Build) dev (64-bit)) on Win 10.
I see an advertisement pop up suddenly from Brave. Is this related to Brave advertisement and Brave rewards?

Almost certainly. We have a state-management issue with Rewards and Ads in dev right now, which we could definitely use help tracking down. Main thread is here: https://community.brave.com/t/are-you-seeing-brave-ads-without-opting-into-the-ads-program
