I have two Rise Vision accounts. One plays hosted links from dropbox and drive just perfeclty, the other account flat doesn't. What is the missing step here to get my second account working off dropbox and drive as well?
It's hard to say just from the information you've given me. Are the images set to appear on both displays? What are the differences between the two media players? Are they both running the same player?
With those questions out there, I will mention that dropbox is generally not recommended as a host for images/video content. We have had instances in the past where users have used dropbox as a host and their accounts have been blocked or throttled.
