Got my new card in the mail today (or maybe yesterday but I just checked today)! 14-15 days. It was way faster than I thought. Thank God! Timeline as follows.
May 16 - Submitted renewal application online.
May 23 - Status changed to Completed, but I only found out on May 30 per inspect mode which I learned through this forum. No rejection.
May 30 - Tried to link application to online account but the system only found my initial PR card application created after I first landed years ago. I could not link my renewal application.
May 31 - Got my new card in the mail.
Never got any email/AOR or application number. Never able to check status on CAS tool. Status on PR Portal remains Submitted. Still unable to link the application.
Hope that helps. Good luck!
