Well, bad news.
I found this in the support site for App Studio:
The particular ConnectKey App (.weblet file) is then be saved to the folder used for downloads for the browser.
When an App is saved to a folder from the Xerox App Studio, it must then be installed from the device’s Control Panel or CentreWare IS, and will no longer be able to be installed from App Studio. If a copy of the App is made using Save As, the copy can then be installed via App Studio.
Which means it will be impossible for me to create you an app for Box, or get one to you by this forum.
So App Gallery can't work on your 8900, App studio apps work as long as they are to go local and not to dropbox/box etc, for that you need access to App studio to push it to your device, I can't get you that, and since I don't have the device in question, I also can't guarantee it would then install (That may be what you were trying when this whole support post started for all I know)
Are you trying to install the apps. via App Studio or App Gallery?
Please let me know. There is a difference with the apps.
Thank You for your help.
I have created that BOX workaround a couple weeks ago. It works, but we do have that machine logoff issue. But I could probably resolve this. I will call a tech support guy to try the wireshark idea. Also I am attempting to gain access to App Studio vs App Gallery.
Yes, continue to work on getting the App Studio account.
Once you have that, you should be able to install apps on the Color Cube.
Please keep us posted.
