Hi @sup_rana I think there might be some misunderstanding.
If you have a verified Uphold account connected to Brave Rewards, you should not be seeing a claim button. If you are seeing a claim button, then your rewards wallet is in an unverified state/not connected to a verified custodian.
Can you please submit the information surrounding your issue to our form there so we can take a closer look?
Submitted the necessary details through link provided by you. Please note i have only 5days left to claim some bat. The sooner i receive resolution, the better it will be. I am also attaching screenshots to show my wallet is verified still I’m seeing the claim button and finally the claim is being unsuccessful.
