Cryptomator not showing all my files?

I use Dropbox as my cloud storage provider. I downloaded Cryptomator to my MacBook Air with 2TB of storage capacity, created a vault in Dropbox through Cryptomator, moved all my files there (about 1.5TB of data total). All seems well on the MacBook.

Downloaded the Cryptomator app to my iPad and iPhone, mounted the new vault but Cryptomator is not showing all my files. I’ve noticed that it is my larger files that are missing (those about 1GB and over).

Why is this?

Also, on a separate note, when I download Cryptomator to my Windows PC and mount the same new vault, it creates strange duplicates of files beginning with “-.”.

What’s that all about?

Did the dropbox sync finish completely on your MacBook?
