Ellie - the application was submitted on the 7th April and is waiting to be processed. It hasn't as yet been expedited. Unfortunately the request to expedite was submitted through the wrong channel so has not been seen until I was prompted by your post.
There's a dedicated channel for expedite requests -
Request an expedite - GOV.UK
I'll flag with the casework team to expedite it and that should mean processing starts asap from today
