Gumtree disappearing/unpostable ads

Absolutely pathetic website to sell on. I've easily tried over 20 times now to post my ad. I reached out to Gumtree support and they said my account was clear to post the ad. And still nothing, just doesn't give any reason. How can the error handling of this website be so bad?! At least, tell the user what they doing wrong. There's absolutely no guidance on how to post on this terrible website except try bang your head through the wall. I really don't know why we stand and keep supporting Gumtree when it's just got such a bad user experience when posting an ad. I wish I could get back 2 hours of my life which has been wasted on this website. I'm off to FB marketplace. This is ridiculous. Future sad user...piece of advise, if you ever find your ads disappearing when trying to post...spare yourself the agony and just close this website. Really time to boycott this bad websites that waste users time, we're supporting trash
