General Feedback on 6.2.3/6.2.4

A few questions for the cloud environment:

For test purposes we have a ReadyNAS 102 with the 6.2.4 release.
We are testing it in a private cloud style setup,
office with the ReadyNAS, access via "Remote" from Windows+OS-X Laptops, as well as Android and iOS systems.

What does not seem to work:
ReadyCloud android client
-> only shows files
-> no not modify/delete existing files, downloaded+edited files are not reuploaded
-> no way to upload new files to the nas (Only automatic pictures upload works)

- ReadyCloud windows client:
-> On a remote laptop it sees the NAS, but is silently unable to establish the VPN
-> On another dekstop system, after installing the ReadyCloud client all network connectivity lost

- ReadyCloud OS-X Client
-> Does not yet exist, even as featured in the documentation

- ReadyCloud Website
-> Does not remember/autodetect webbrowser language, always switches back from german to english
-> Password reset does send a link, but setting a new password results in two red password fields, with no explanation what's wrong
-> Password reset does not work
-> Only the top-level folders of the NAS are displayed, navigating down does not work

We haven't yet tested the iOS client, but with the above list we are not very motivated to do this...
