I've received my GCM notes yesterday.Myself as well. They've requested biometrics for my wife. We submitted the biometrics and it's showing on our application but status still remains "Your action is required". I submitted a webform over a month ago and still no response !
I'm assuming no one heard from London VO lately ... ?
My file was transferred to London Visa office on 21-05-2020, but no progress since then. I've read on this forum before about London visa office that they process applications very slow.
