Since my last QB update was installed, I am having a similar issue to the one originally reported. I have a single user license. My invoice numbering system is simple, based on the date and a sequential numeric tag for the invoices entered on the same date. Prior to the update, I only had to manually enter the first one and then QB would automatically apply the sequence. Now, I manually enter the first number. Then QB seems to be applying auto-sequence for me but when I recheck, it has changed the first few characters to '100409' instead of '190409' (for example on 04/09/19). So I have to constantly recheck and re-enter the correct invoice numbers. Is there any way to modify this new behavior? Or any insight into why this change was implemented? Very disruptive.
