This is Online Application. So 13 days policy is calendar days or working days. She has a flight next week and I am really concern now as I think she won't be able to make it by that time.India has a big load lately, as seen on forum and people are getting emails from IRCC stating the delays due to large number of applications. Check your emails (inbox and spam) for any such email.
Also, since the biometrics are done on 26th so technically processing started then. Wait for 13 days (the estimated processing time) from 26th and the raise a CSE.
Was this an online application or paper?
I didn't get emails regarding delay
