I agree with WBAdminUser. Me being a software developer as well, beta usually means function complete, but untested. I fully understand the situation with Amazon being a culprit for the status with the use of their Unlimited Cloud Drive. But I have no understanding in lacking a proper Dropbox support - them being of one of the first of its kind back in 2008 with a crazy userbase today. And their API documentation is really complete and tested by a dozens of 3rd party developer, their support towards helping programmers to develop for their platform is IMHO unmatched.
The other point of getting no reply to my problem from the developers here is quite unusual, seeing good discussions on various other topics in this forum.
