The link does show the most recent update date but does not show 'what' got updated on that day. This update you're referring to came on the morning of 07/10. I travelled from the US after that and know several people who did complete the process. There's no reason for them to deny you PR status if you tell them that you are moving permanently. Once you have a counterfoil, its incumbent on them to award you as a landed resident. You may go back after that as there's no check/stop on your exit. But yeah, you might be stuck in US then for an indefinite time and unable to come back to Canada considering how well we are doing there with regards to COVID.
U-turns always pissed CBSA from day 1, COVID has nothing to do with it. But they still entertained those and they are still getting processed as per people who have posted here (would have to agree that this depends on the officer you encounter)
With all the +VE experiences, taking a risk to land was worth it for me as compared to waiting endlessly and anxiously for the COPR extension, which we all know would involve additional cost and time.
HTH
