Congratulations to those who secured an II! You'll do well 🙂
As for others waiting, unfortunately, I can't provide you with a defined timeline of when you'll hear back. Admissions is largely a black box with so many factors involved (i.e. are you with a linkage program, who is reviewing your file, how far behind your reviewers are etc). Personally, I got an II a month after submitting my secondary in middle of July 2021. So use that however it suits you.
As for the decisions after submitting the application, the most often will be a "hold". This is not me being pessimistic, but just reality, since there are way too many applicants that interview spots and eventual acceptance. Rejections after submitting a secondary (at this early in the game) are super rare.
Hope this provides some more insight.
For those who messaged me, I'm sorry for my late responses. School has been getting really busy. I'll try to respond as soon as I can, but need to prioritize my studies first.
Good luck everyone 🙂
