Items not posting on website

Hello- new to POE2, so this may be user error. I bought a premium stash tab to start selling items. When I got to the trade site after listing an item I don’t see my item. I’ll type my username, with the numbers included, and the items I have for sale don’t show.

I think the site syncs with the premium tabs when you change zones. So if you stayed in your hideout/current hub while checking it won't update.

*not certain about this.
