Coss is available on blockfolio, did you try to sync the app and also download the latest list of coins and see? I have added it to my tracker list, should be working for you too.
Thanks, I will try.

COSS team, Can you add COSS/LTC trading pair? Both Bitcoin and Ether are clogged up and take many hours.
COSS & Litecoin, now that's my favorite combination
Second this, would also like to see faster crediting of LTC deposits.
