I applied in mid July 2018, my medicals were approved on Dec 2, 2019 and have not heard back.
Yesterday was one year that my medicals were approved, so I went into my account and noticed a ghost update (notation that my file was updated but no changes). I only noticed that the notation that my medicals were approved disappeared. It also now says they will let me know if they need them.
People in the Facebook group said this happened when their medicals “expired” and later on were extended to the same date but on 2020 -for example, approved Dec2, 2020. I checked today and is still as yesterday (no medicals)
