Can you advise specifically what you changed? I know I was looking for specific words but the text in current flags are different. Such as they said Enable pop up ads but that doesn’t exist. There is Enable Brave Ads custom push notifications but I’d rather not just assume you equated those as the same.
Then for Allow Brave Ads to fallback from native to custom push notifications, that’s still a thing. So if you’re saying you enabled that, might be it.
Just want to see specifically the changes and then suggest for others to try, to see if it works.
