Originally, due to Important: Uphold no longer supporting countries in Russia, Ukraine, Belarus, and Balkans region
I do see what you’re mentioning that it’s no longer listed at https://support.uphold.com/hc/en-us/articles/360026786712-Non-Supported-Geographies-
I’m guessing Uphold just hasn’t contacted Brave on changes and allowed for connections. Guess might be good to tag @steeven and @chriscat to see if they can look into it a bit more.
