This happens when the funds 'Available to Withdraw' are lesser than the amount you were trying to withdraw or the total amount in your Groww Balance.
Note: New amounts added to your Groww Balance will be 'Available to Withdraw' only after 1 working day.
Your withdrawal request may have been processed with a lesser amount than requested because your Groww Balance was insufficient.
This could be due to unsettled DP charges from previous trades or an increased blocked amount due to changes in margin.
