Okay I'm going to reply to both of you here.
First, it appears IRCC is still working on mid-late April applicants, so it is normal that both you have not received any communications from them. Based on the current processing time,
@okbangaram you can expect your AOR in maybe 2 weeks if not longer, and
@returningPR2016 you can expect something in late-October or early November if not later. Again, follow the thread in the forum, and the processing time published by IRCC to get a general sense of your approx. timing. This is only for reference and nothing representative. If you have confirmed your documents have been delivered to IRCC, you are good, wait for them to contact you. Nothing much you can do to expedite that at this time.
Second, an expired PR card
does NOT affect your PR status whatsoever. As long as you are in adherence with the RO, you are good. End of story. You can't enter with an expired PR card by air, boat, train or commercial buses. But you can come back with private vehicle, for example, you drive yourself back with a rental car. You can expect some questioning at the border that they ask you about your expired PR card, and they just verify your RO compliance on spot. Nothing else to be worried about. If your buffer is good (way above 730 days presence), there is no need to concern. An expired PR card does NOT mean you are no longer a PR, the only inconvenience is that you might have some hiccups when travelling, especially by air. Maybe some provincial services can be impacted depend on where you live. But in Ontario they accept expired PR card as long as it was expired less than 5 years ago.
@okbangaram if you really need to travel somewhere, a PRTD might be helpful - look into it.
