Hello , welcome to this group.
There is no specific tracker for LVO, for more updates you can join the fb page for LVO spousal applications there you can follow other group members who have similar timeline as yours.
After Aor, Lvo takes 8 to 10 months to process application for PPR, and after medical it takes 5 to 6 months.Once medical and biometrics are done there could be absolute silence for your entire application process or you can recieve request letter regarding any additional documents which is generally related to your eligibility.
