@mellem The error you’re seeing is something different. Currently being able to connect to Uphold has been paused for everyone and the device limit error is sometimes shown because of that. They are hoping to get it resolved this week. That said, even once that’s done, I’m not sure if you’re in one of the currently supported regions.
For more details on it all, please go to PSA: Unsupported Region and then click on all links you see. Be sure to read it all, don’t make assumptions.
