Some information about
Application Assignment due date:
Application Assignment due date is the same date as the date that the call center agents tell you to wait till then (maybe + a week). If you didn't hear anything by that time or a week after, call them back and ask about your application.
What happens is that the officer receives a reminder for file that dues that day. If there is anything new on the application, he will check it and proceed with the next step. (for example,if he received the results of your criminality, he passes it and hence a ghost update. A lot of ghost updates happen on the due date.) If not, the due date will automatically be pushed back for one more month. (Of course not all officers care a lot about due date. The officer may also be on holiday that day, that is why it is not always followed)
Yes, there is no guarantee that your file moves on the due date, but the important point is that it is highly possible that your file won't be touched till next due date, so you may not worry that much in the time between.
Now what call center agents tell you is to call after that date, if there is anything new, they will tell you, if not, the due date is updated. They then tell you to check by the new due date and call them again. This vicious cycle goes on and on.
