@jwalantsoneji just to be clear, Uphold tells you that your region is not supported or you’re getting the Region Not Supported message when you’re trying to connect to Uphold from Brave Rewards?
The reason I ask is if it’s the latter, I’m assuming the reason is you aren’t originally from Canada. The API that is used to communicate between Brave and Uphold uses your passport to share what country you’re from. If you created an Uphold account with a passport from a country that isn’t on the list at https://support.brave.com/hc/en-us/articles/6539887971469 then you’d get the message not supported. You would need to get a Canadian passport and have Uphold update that. A change of address through Uphold is not good enough due to the API using the passport.
