It’s still there for me on both app and browser

its glitchy so try again 

also try “continue without a match” after you put title in and hit enter /search

I tried a few and it wouldn’t show the advanced options (browser) but it did after a few more dummy listings 

i wonder if those sellers who haven’t had their items switched to SD yet can still access custom (like me)

or whether it’s  pot luck 

actually it’s pointless wondering ..could be anything 🙄
