The space for check no. is still blocked in incognito bowser or any other browser. The following module: check, pay bills - the check number is blocked and the "header say "Check no. to print". I do not need to print any check since I am using a physical check, I am just recording in QBO Plus the issued checks so I need to input the check number in the box for check no. inside the transaction window either in "Pay bills" or "Check" module.
