@ProGamingKID I’m not sure why UAE isn’t able to be connected, but guessing between Brave and Uphold, they determined it not able to be done. Sometimes they’ll limit integration based on regional activity and risk, especially around things like fraud or budget.
In any case, Brave is shifting its attention to on-chain payments. I would suggest you read through everything at PSA: Current and upcoming changes to Rewards and Creators when you can.
