Hi All,
Here is my timeline and experience with PR Card Renewal online:
Submitted application - September 19th, 2023
Status changed to "Incomplete Application" with all buttons greyed out - October 20th, 2023
Renewed card received via post - November 10th, 2023 (status of online application still unchanged).
My new application for the PR card cannot be found and attached to my IRCC profile.
Obviously, there are bugs in the online system, so don't get discouraged when you see no status change. Follow the requirements provided by the official website and you will be fine.
