Hey, looks like I’m late to respond here. Sorry about that JHD. Have you figured out the answer yet?
If not, answer is South Africa is among MANY places that are restricted from linking Brave to Gemini or Uphold. The reason why one was verified is because you happened to link it prior to them preventing it, meaning you’d receive payments from that device until you become disconnected again. As to the other one which was disconnected, it wouldn’t have verified because of the new region restrictions.
They are planning on bringing back regions when they can, but we’re still looking at months before it happens. You can read more details at PSA: Unsupported Region
