I’m having the same issue too, I’ve just listed both mine and my partners previous phones, my phone listing was initially live, I then went to list my partners phone, that one goes live but then the listing for my phone is no longer active, I tried listing it again separately, only to get the exact same issue, yet my partners phone listing it still active. I’m $11 out of pocket now and want my money back. I’ll definitely only be using Facebook from now on. TradeMe is just useless and ridiculous.
