You are the same as me. I got medical request and on the same day my eligibility was completed. Also, please keep in mind that the tracker is more accurate as it shows the exact things which happen on your application. So, if your eligibility has been completed on the tracker but it is not on GCKey then do not worry. Your eligibility has definiately passed.
For me the TRACKER SAYS:
Biometrics completed
Medical completed ( it was requested)
Eligibility completed
BG in progress since my medical was requested on September 7. BG has been in progress for over two months. I am really worried that I have been put into security screening. I do not know how long this BG is going to take.
