Myob Accountright - No Alert you cannot save work when two people work on the same invoice

Hi, We use Myob Accountright and have noticed we no longer get a 'cannot save' error when two staff members inadvertently work on the same quote or invoice at the same time. 

This seems to have changed in the recent update where the bank feed issue occurred.

Previously, if two people opened the same invoice or order and worked on it, the second person would get an alert when they tried to save their changes, saying the invoice / order had been changed and they cannot save their work. Now, to the employee it appears they have saved their changes, as no alert appears and they only find out later that this has not in fact occurred. This has caused significant issues until we worked out what was happening and now to overcome it staff have to ring each other to ensure they are not working on the same sale.

I'm wondering if this is scheduled to be fixed please as it is a significant problem?

Thanks, Regards, Judy.
