Dear Upwork Community
Unfortunately, like many before me, I have had problems completing my freelancer profile and it remains incomplete. I would like to delete/cancel the profile so that I can figure out how best to compile my account and get approval. There doesn't seem to be a simple way to do this and so I am hoping that an Upwork moderator can review this and help me, ultimately advising those in similar situations.
I look forward to your assistance.
