Did you order gcms notes again before it finally started progressing?
I ordered two GCMS notes, once in May and once in August which returned basically identical results (nothing changed), but I'm certain that my GCMS notes request had nothing to do with the progress since it took another 3 months before I got any updates.
In October I got an ADR for CV and supplementary info, and once that was submitted in early November, I had been getting GUs once every 2-3 weeks: First a webform response mid Nov telling me Eligibility and Criminality Passed, a GU Early Dec which may have something to do with my BGC, then yesterday a GU where it appears my Expired medicals are being sent for reassessment.
