*Issue*
Driver often found that the signature is missing from their app and they have to manually sign it themselves when they open the app again
*User Story*
# Driver accept booking, arrive at the pickup point, slide to sign, app loads for a long time
# Driver kill Deliveree Driver app / restart their phone
# Open up their phone again then resume the booking, slide to sign, signed by customer, then continue to next locations
# On their way / when they arrive at the next location, Driver open the app again and found that the first signature is gone.
