Most items not being listed on trade site

I have a number of premium quad tabs that I use for listing items. Since a few days ago, I noticed that majority of my items are not selling and I kept checking if I priced them competitively. I noticed that most of them are not showing up on PoE2 Trade at all. I tried playing with the tab settings, from exact price to best offer, changing tab to per item price instead of same price on all items... pretty much everything I can think of. Nothing seems to work. I reached out to Support, and besides an initial reply asking if I was using the right trade site, it's been radio silent. This is getting pretty frustrating, and I'm hoping someone else can tell me what I'm doing wrong.
