Back to normal now. As usual, the useless eBay live chat staff were telling me that I am wrong and that this is normal, when the problem was magically  fixed. As I was taklking to him and he was repeatedly insisting that items take up to 36 hours to become live, I tried listing a sticker and it went up straight away. I wish they would listen to their customers instead of reciting lines from their script. eBay used to have great customer service, but it's been awful for the last 10 years or so. I used to be able to ring an Australian staff member who would fix my problem within minutes. Now I have to spend hours and hours going around in circles and achieve nothing. I pay enough in fees for them to hire a full-time operator, so don't understand why I can't get decent sservice. I get better help here.
