Welcome to the brave community friend!
Ok, Are you concious about how the ads work?
There appear just 4 per hour that will give you bat (You can spam open new tabs in when the hour passes), after that, ads will keep appearing but won’t give you BATs.
I readed here that the limit of recieving BATs per day is 20 or what your country catalogue (Which I don’t know how to see) is exhausted. Eljuno is a Brave Moderator, so it’s true.
Also, when that happens could be your internet connection, the ad will show but won’t give you BAT, I suggest if that happens to open tabs until the ad appear, wait a second, then open a new one and check if the BAT is rewarded.
And theck this thing is activated, or the system won’t give you BATs:
And I suggest to enter in the button at the right of that and pur the ads 5 per hour
Hope it helps.
