I believe this is still occurring (the hidden listings weirdness). My
listings are NOT promoted. They were showing up on desktop/Chrome until
(I noticed) today. Interestingly, when I first hit Search I can actually
SEE the listing come up momentarily...
Completely agree - this is a bug and it is throwing off not only my
selling, but also my purchasing/searching. I also search by newly listed
and can see very plainly that things are not as they should be in the
categories I research.
