I got less BAT than I expected

I have 4.440 BAT in my Brave Browser but @BravePublishers only sent 2.71 BAT to my wallet. Where is the rest, is it normal?

Most likely. This month payout is for BAT earned in March (1-31). And BAT earned after that (1-30 April) will be paid in May.

In those cases, you can check before the 5th day of the month(the payout) how many ads you have seen in the actual month. You substract that from the estimated bats you will have, and that’s what you’ll recieve (that are the ads you watched from 1st of the past month to the last day)
