Two issues when using inoreader in the Brave browser, first is a message when opening the page saying I am blocking adds, second the place holders for ads are still active.
I have tried the same webpage in Opera, Chrome, and Yandex using the Adguard extension and they do not have a problem.
Here are two screenshots taken in Brave
This is what it looks like in Chrome
Brave version: 0.60.45 Chromium: 72.0.3626.109 (Official Build)
Running on Manjaro Cinnamon.
