Dear all, I have created a Google Presentation. I have a Google Chromebox running Rise Vision App in Kiosk Mode. I have created a RiseVision Presentation existing of only the Google Presentation (no Goadgets or other things). This presentation is displaying correctly since July this year. Suddenly last Friday it stopped running well. Now the Rise Vision app only shows about 4 to 5 slides (out of 40) well, all other slides are displayed as a black screen. When I run another presentation on the Chromebox (via RiseApp) it works well. When I run the problem Presentation on another Chromebox it has same strange behaviour. So the problem seems to be in the presentation. What can be wrong? Do you have any ideas, how to troubleshoot? What might have caused the sudden problems?
