Yep, mine has disappeared too and I definitely checked it yesterday morning and it was showing fine. Bit concerning, I really hope it's just because they are updating it, although i'm not sure why they have to take down your current position, surely just replace it with the up to date number when it's ready? Praying they have not mucked it all up, heard some horror stories of lost positions, and it's been a long 20+ year wait for me.
