I've seen some movement on late 2020 and early 2021 files. Many of these guys are recommending going for an upfront because that's what they did.
Personally, I've waited since October 2021 (when my meds expired) for a remed request and it's quite annoying to see apps with very recent expiry dates for their meds get PPR.
I have just gone ahead and booked an appointment for next month (earliest date I could get, because it seems like people are starting to catch on) and let's see how it goes.
If I get a remed request before then, perfect, if it's PPR by some stroke of luck, even better, and if nothing, then I hope this upfront triggers some activity on my application
