Mine is the same “ due date pushed by 30 days”I finally got my CBSA notes ordered in Jan. I still didn't receive the notes from IRCC ordered at the same time. Good thing I applied for both at the same time to see which one comes first. Anyway, from what I see, the movement in our case was triggered by the email to the local MP. Prior to that, the notes just kept saying on many lines "due date pushed to 30 days" even after having everything passed. Imagine that! They just kept sitting on it as they couldn't be bothered to send a request for updated PCCs, Schedule As and Remedicals. All of which expired because they were sitting on the files in the first place!
Might be worth a try to write to the MPs to speed things up for those waiting for a long time.
Do you know how can i find MPs to contact??
