Not “quite a few.” You have had 12 ads. For that your have an estimated range of 0.036-0.065 BAT. So divide each by 12 and it’s 0.003-0.005 BAT per ad.
Not sure about your region,. but I see a lot of ads that pay just 0.005 BAT per ad. If some of your ads seen were of Brave products, then that “dilutes” things where it seems lower average.
But based on what you’re sharing, everything seems to be working perfectly fine. You are seeing ads and earning BAT.
I also gave you a resource in my earlier links that you can use to check ad campaigns, what they pay, etc. You can try to track it yourself a bit.
And in terms of you only having 0.00 BAT in your Uphold for now, I’m not sure how long you have been using Brave. But assuming you connected last month, then you would be receiving the payment for what you earned in the coming weeks. Our estimated earnings have always decreased to 0 when new month begins because it’s a new month. Then the payout for the prior month starts around the 8th of each month and can take up to a couple weeks to process (though they usually try to have it to us in a matter of days). So you would see a balance posted when the current payout completes. You can track that status via Ads Payout Status Update.
And of course, if you withdraw from Uphold when you receive it, then the balance would reflect 0 as you removed it.
