wallet key changed between brave and uphold

Hello, I am sending you this message because I have a little problem with my account uphold and brave. My wallet on Brave is no longer connected to my wallet and has been for 6 months now. I don’t know how this is done my 2 keys no longer match. You could change the id uphold with the new while keeping access to the Basic Attention Token that I had already recovered a few months ago. Thank you for your understanding and future response
