Cons
Con Requires advanced command line knowledge
In order to use dm-crypt you need to have advanced knowledge of Linux and of the command line, as well as the Linux filesystem.

Con Android version is paid
Con Bugs with deleting of files
Sometimes files cannot be deleted and there is no working solution/fix available yet
Con Current WebDAV is a buggy on Windows
The used WebDAV implemention shows wrong available capacity and has a limitation in the file size. The developers are aware of these problems and working on a better solution.
Con Compatible with Android versions 4.3 and up only
Con Slower speeds
Encypting speeds are slower then regular uploads, larger files particularly video files often cannot complete transfer without errors.
Con No camera upload functionality
Cannot automatically back up photos on mobile devices replacing the need for Google drive or iOS fully. User then has to go and either manually select photos for upload or use cloud service and then encrypt defeating the purpose on mobile clients.
