Is there a way to separate/see what you have invested and what you have earned or lost
Please go the fund you wish to check and then tap on it. You will able to see the total deposits to that fund and the overall earnings/loses.
Also are your returns daily ? And how long does it take to re invest
Any profit or loss is added or deducted from your fund balance, this is updated once a day. And as you correctly mentioned they are invested along with the rest of the funds.
