Why is a token not listed on CoinDCX App?

Updated 

CoinDCX App is a simpler version of CoinDCX Pro (app/web) and an extension of Insta on CoinDCX Pro/Web where users do not have to wait for the execution of their orders in the market.

If you cannot find the token on the CoinDCX app, you can check the web platform or the CoinDCX Pro app.
