This feature should be returned. With uphold being able to freeze accounts if you are not in the US, if your country happens to be temporarily not allowed (or with worse luck, if laws happen to get in the way, permanently), you won’t be able to interact with your funds. You won’t be able to back them up to begin with if you are just signing up and your country is temporarily listed as not supported.
Uphold is NOT RELIABLE. Having users to backup at their own needs at anytime via the browser itself is a godsend. Why was this disabled anyway? I’ve lurked around and saw a user on reddit that’s a part of the BAT team and said this was an issue and everyone’s looking into it.
