Here is one link to order GCMS notes:
https://www.canada.ca/en/immigration-refugees-citizenship/corporate/transparency/access-information-privacy/request-privacy-act.html - If you are in Canada right now, you can do so under the Privacy Act. If not, I believe the sponsor can do it on the principal applicant's behalf under the Access to Information Act.
Thankfully, my application was never 'missing' but due to a clerical error at IRCC, correspondance intended for the sponsor was sent elsewhere. The notes allowed me to see that, so we called up and gave them the correct email.
We sent our application off in July 2020 as well. Of course every app has a slightly different timeline, but I would expect that most July applicants should have received
something by now. The GCMS notes might provide some clarity (if you can even order them without an app number -that I do not know).
