Triplets, actually! Well, roughly.
I think I posted this back in the old thread some months ago, but I'll repost it because it doesn't seem to have come over in the list (on which note, thanks for the list! Very interesting to see how this is all progressing for everyone):
28/10/18: Online application submitted & fee paid
24/11/18: Supporting documentation posted
26/11/18: Supporting documentation signed for
26/02/19: Receipt acknowledged by email
If I hadn't known they'd signed for it in tracked post I'd have been concerned the documentation was all lost!
