I personally believe that there is no delay, and you will soon see that the status changed, it will then move fast. I was looking at some of the timelines that ppl are posting on this thread:
PR Card Renewal & New - 2022 Processing Timeline some of which are for online submissions, I see one person who submitted early June, got AOR after a month, then after a week his card was sent for delivery. I think all this waiting time with the status at "submitted" is part of the 60 days expected timeline to have a PR card renewed. Once you have the AOR you can then track progress in ecas.
