Hi, you're not doing anything wrong.
Your auctions are there, but unfortunately there are lots of "featured" auctions above yours
Seller+ members pay an extra £1 to have their items "featured"......but this means that (at the moment) the first 1.5 pages are all featured auctions.
I have found 1 of yours (a Samsung) on page 2.....but am pretty sure that the rest are following iykwim.
Does this help?
