Brave settings returning to default after closing and re-launching the browser; this specifically relates to the Brave "Trackers & ads blocking" and "Block fingerprinting" settings in "shields"

@Abug please accept my apologies for this inconvenience. Please go to brave://settings/clearBrowserData > On Exit and make sure that Site and Shields settings is unchecked to see if this solves the issue.

Let me know if that works.
