I can't and haven't been able to search marketplace for as long as I can remember, I didn't really mind but now that I am trying to sell stuff I'd like to get some price ranges but whenever I search for something, even generic like PlayStation or bike it says "no listings found", now I know for sure that there are listings as I just clicked on them, but when I search it shows nothing.

So what's up with that, facebook help centre is useless with this, I remember they used to have a help centre that was somewhat helpful but now it's all algorithms and BS.
