Invoicing
Revert to standard invoicing until the problems are sorted out. Each entry has a 5 second delay before it is entered. Even this message is doing this. It is currently almost impossible to work with as a bookkeeper. It jumps aaround all over the screen and with the delays one then has to go back and find the field. It is not my computer. Other screens are not a problem. I read somewhere there are going to be changes to payroll. Please test the changes before this happens with this also.

Hi Pauline, I'm sorry to hear the slowness you're experiencing. I want to be transparent that we will not be bringing back classic invoicing. However, I'd highly recommend raising a case with our team of specialists at Xero Support who can investigate what may be causing this for you.
As you've also mentioned experiencing slowness when engaging on product ideas here, while you wait for supports response I'd recommend starting with the troubleshooting steps in our article here.
