You haven't yet done so despite being told to update your signature by massage. So you are disqualified from the campaign.
October 18, I got accepted (have learned it thru PM).
October 19, yesterday. I updated my avatar and signature campaign.
October 20, received a PM that I was late in updating so they removed me.
Not a big deal to me that I got removed for a valid reason. But that was an unprofessional approach. Not interested in joining anymore. Good luck to your campaign.
