Brave ads deactivated and no connection to Uphold Wallet

Hello,

I am using the recent version of Brave at Samsung Android and two notebooks with Windows 10. In the moment it was only possible to active ads and connect to uphold on one notebook.

I cannot active ads (the button doesn’t work, nothing happens) and I cannot connect to my Uphold account. I had a full reset of the notebook and had to reinstall Brave, but reconnected.
Sometime last month it has to be an error. I also didn’t get the normal amount of rewards, so I looked it up…

I also tried to login at Uphold first and tried to connect the Wallet afterwards. Doesn’t work.

Maybe I need to unlink one Brave Account from the Uphold Wallet? How?
I have no access to possible old Brave Accounts
