I am basically in the same situation. I haven't received any updates since my biometrics submission in mid October. My case is complicated because my fingerprints are of poor quality, and the agent mentioned they would include a note explaining my skin condition. In my GCKey account, it shows that IRCC hasn't received my biometrics. However, all my biometrics information has been updated in my profile. I have called them several times, and all the agents confirmed that IRCC has received it. Additionally, I sent a webform, and they replied confirming it was received. In my tracker, both biometrics and the background check show as "in progress." However, in GCKey, the background check shows as "not applicable," and the biometrics section says "not received. I am unsure which one is accurate.
