@IambicRhyme OfferUp sends you a email to the email you used to signup. In that email is a Link that you click, then you sign in from that. Close everything then sigh in again and that’s it. If that didn’t happen then something went wrong. Is there a link that says send again? If not then you need to contact support and they can resend it to your email again. Let us know if it doesn’t work. Good luck my friend.
