Hi,
I am in the same boat, i called the Toll Free Number couple of times and every time they say it is pending for officer review. I got standard letter on September 3, 2021 with the same thing "if you have not submitted form5768". Initially i forwarded them original with the package, but to be on safer side i uploaded again on web portal the same day, but after that nothing.
It all depends on Visa officer. Those who are getting, their Visa officers are proactive and fast. Good luck to all who got medicals and Biometric.
Our is waiting game.
