“Hi Muhammad,

Thanks for your email. After verifying your ID proof, I am happy to let
you know that I have manually overridden your PIN requirement and you
won’t be required to enter another PIN for this account in the future.

Going forward, please keep in mind that if your payments are on hold for
any reason other than PIN or phone verification, you’ll need to remove the
holds prior to the 15th in order to be paid in that month. Otherwise, your
outstanding earnings will roll-over to the following month and you’ll be
paid out according to our normal payment cycle.

Once you’ve removed any additional holds from your account, you’ll be
issued a payment at the end of the first month after your balance reaches
US $100.”
