谁能用中文帮我解释一下下面这段英文是什么意思?
Hi AXXX,
We’ve finished our investigation on why those
reminders were being sent.
Whenever the project list item updated while
the status of the project is Completed and the survey has not been sent yet,a
reminder will be sent to the project director.
This behaviour is hard-coded and can’t easily
be changed.
Regards,
XXX
