I have a problem with Cortez wallet: I'm trying to transfet my XTZ to another address, but if I put my whole balance, at the moment when the fee is calculated I get an error message (com.android.volleyServerError), I have to remove the decimal to make it work, and at that point the calculated fee is not sbutracted, but added inb the final amount olf the transfer.
Example, let's say my balance is 100.333, if I try to transfer the whole amount I get the error message, if I try to transfer only 100, a fee of 0..001 is calculated, and I get "pay 100.001" on the transfer button.
What am I getting wrong?
