Newbie here, I can't sign in my Brave Rewards

I don’t understand why I can’t log in my Brave Rewards on my brave browser.

I’ve already been verified for a long time, and I can sign in my Uphold account, but when it comes to may Brave Rewards sign in a pop up error always stop me from signing in " Error: Region not Supported"

I don’t know if it is another bug from brave or what, is it going to be fix?
Everytime I have to check my rewards there’s always a new error coming in and I’m so dissappointed.

I hope you will fix this soon, or can somebody enlighten me what is happening.
