I applied since October 2020 did my biometric same month since then am yet to hear from them but i applied using the old GCKeyHi, I am in the same boat as you. I applied for my parent's visitor visa through GCkey. I got to know today that there is another portal for visitor visa which is supposed to be "faster" than GCkey.
Although I am scared myself but I can tell you about my updates so far:
File submitted on 22 Dec 2021
Got BIL within 24 hours
Got Biometrics appointment for 05 Jan 2022
Did biometrics and it got updated within 24 hours on the file.
It now shows that Biometrics are completed.
I know my details are not very reassuring to you at this moment because the real wait begins after biometrics. I don't know what will happen going further.
I don't know why IRCC has created this confusion. If they started a new portal, then they should have stopped taking visitor visa applications via GCkey.
Please let me know if you find out anything new and I'll do the same. We are in this together.
