Haii! Coin tu biasanya ada kat wallet section app tu, dekat bahagian rewards atau points, tengok kat tab bawah or menu utama lah, normally ada icon "Coins" atau "Rewards" sendirian, sometimes grouped dengan vouchers jugak. I'd suggest go through settings atau help section in the app itself sebab each platform layout dia berbeza sikit, tapi usually corner tu lah tempat claim rewards!
