Hi Philip,
I'm afraid that right now you can't change the hardcoded dc thing. I'm sorry. This is something that needs to be fixed asap. We will fetch the current dc configured by the user or we will let the user to pick one.
Anyway, please check if everything else is fine, becasue even though using that hardcode dc is not a right approach, things should work. Or at least, tell us what the problems are.
Thanks
