Unable to link uphold and brave

Hello, i recently saw that my brave account is not linked to uphold, altough it was before.

I think that’s because i created like 3 uphold account at the beginning, and they “merged” them into one, which is different from the one registered in brave.

Can i link my brave account to that new uphold account ? When i try to register it says “fonctionalities limited” or something like this (my browser is in french).

Thank you for your help
