Principal applicant: Eligibility and BG - In progress (before recent update eligibility status was not started)
Dependant: Eligibility - Not started and BG - In progress
Tracker updated yesterday, and now I can see my eligibility in progress. I called IRCC two weeks ago. Eligibility and BG were not started at that time.
This information is correct. We all had UCI starting with CAN. It will be updated to your Study/Work permit UCI after a month or two. No need to panic or withdraw your file.
