So just to confirm with everyone....
Core Payroll has removed the feature to be able to run a 0 zero payroll if employees are not paid in a particular month / week. This means that you have to make manual SUBMISSIONS to HMRC which means that a whole feature of payroll has been removed without consultation or explanation - WE WERE TOLD THAT THE TRANSITION TO CORE PAYROLL WOULD BE SEAMLESS AND EASY! I shall therefore be cancelling my core payroll subscription as now I am paying for a feature that has now disappeared.
There is also a bug in your software which causes you to go around in circles when trying to submit payroll which was not there is older payroll versions.
The quicker they roll back to the old payroll service the better!
