I don't have any issues, the app working properly, why?

Well my wallet never updates, so I have catcoin but ot isn't reflectd in my USD. I did the first withdraw but since then it never updates :s

To speed up the balance grow, you should refer some user with your referral code. I have no issues till now. My usd balance is now over 5 USD thanks to referrals. That's all I know
