EDIT:
I copied my main profile folder (default) in the brave software folder and replaced my “Profile 1” with the copy. When I restarted brave, switched to my second user profile, and created a new tab, it said I had 20 something BAT in estimated earnings. A minute or 2 later I created another new tab to find that the estimated BAT earnings had gone back down to 6.935 BAT, the number it has been stuck on for several weeks now.
Again, any help would be appreciated!
