If you are the principal applicant, then your eligibility completion doesn’t conclude your application. after your medicals are passed and biometric is done you will get an eligibility passed notification in your tracker. However the final decision will only be made once your background check is complete(security ,criminal checks ,admission and misrepresentation etc).
I wouldn’t pay too much heed to gckey updates. My eligibility got completed on gckey in October, whereas in tracker it had been completed in august. Gckey is NOT the place for accurate timely updates(for my case at least)
try not to stress out to much, if you have filled your forms honestly and correctly and there is nothing “wrong“ with your application, it will process in due time.
updates are not daily or even weekly, I would usually get an update once a month, if that.
good luck
