Missing sub-mailbox on a new mac
I have recently got a new macbook pro (early 2015) with El Capitan.
Once I logged into iCloud on it, I realised all my mailbox folders were there, except a custom one that I have made a while ago on my old mac.
I am signed into everything, so I wonder why that sub-folder (sub of Archive) does not appear?
MacBook Pro, OS X El Capitan (10.11.6)
