Hello Team,
I tried to find MAIN company under USA/Financials, or USA/Any.
However I get following:
Same result on web and mobile app.
Seems it is not possible to find without search.
Probably more stocks face this one.
Maybe missed,
So far NRZ, MAIN , from which I found not being listed under coutry/category.
Probably much more 
Also PBA is not categorized.
