Do not reset your Rewards or you will lose any BAT you have. Your Rewards wallet is unverified now. You should disconnect it from Uphold if you haven’t already.
I think the payout issue with unverified wallets is still an issue for some users. The Brave Ads Payout status is still showing payouts are processing for unverified wallets.
Have you updated to the latest version of Brave for Android (currently 1.38.109)? If not, you should update and see if your issue is resolved or if you get any error messages.
Are you getting the claim captcha? What happens when you try to claim your rewards? Do you get an error message? Please update your post with additional information that may help solve your issue.
