(Update: Brave 1.0.52 fixed it)
Nexus 5X (rooted), Android 8.1.0, Brave 1.0.48
I’ve gone to Settings, Site settings, Media, Autoplay, and turned it off so it says “blocked” and there are no exceptions. But videos at m.facebook.com still autoplay as I scroll the page with Shields on.
This problem only started a few weeks ago.
Thanks for the help.
