Cool, got it. I submitted my documents on 7th January. So, it has been more than ~2 months, but my status has not changed. However, I raised several webforms, so those might have delayed this.Thank you! Yes it does feel good, its such a relief and I am sure everyone will feel the same when you all get PR eventually. Godspeed
About the question, yes correct it was saying 'We need additional documents to continue processing your application. We will send you a message with more details.' before that status changed. It took me about a month from the date of submitting my application to get the additional document received status.
Nonetheless, thanks for your response, I have a better sense of what kind of GU I can expect next.
