I cannot for the life of me find a list of my orders on either the Vinted website on my laptop or the Vinted app on my phone. I also cannot find anywhere to confirm delivery, even though (sometimes, not always) I get an email to my email account asking me to do so. The Help Centre and everything I find by internet search says to go to the "Conversation Screen" but I cannot find any conversation screen, not under my profile, not under Home, nowhere at all. I'm not usually incompetent online. Help!
