Well, I just can't. Once you accepted nomination, you're no longer able to update the nomination from 'No' to 'yes' in your application. I guess I have to make a new profile.
I called this morning and talked to an agent. They asked me to submit a webform which I've already done. They told me to wait and wait. That's the only thing I can do now. Btw, I'm not lucky as you, my score didn't get updated after the call.
Hi there! I accepted a week ago. In my EE profile, the name of Nominating province is shown. They also confirmed that I have accepted my nomination, just the score didn't get updated. Hopefully they'll fix it before the next draw.
