Latest Update Prevents Blank Pngs from Auto-playing in Playlists

For several advanced displays, I use layered media zones to preload certain sites that take long amounts of time to load so that the user does not see the buffering, but with the latest update, now blank pngs (which I use to show all of what is below the media zone) will not auto play in playlists. If they are the first item they will load, if you call them with Actions they will load, but no matter what in a playlist within a media zone they will be skipped entirely.

​@WKKBradyn this sounds like a playback behavior change in the Media Zone playlist, and the quickest workaround to try is to rule out channel corruption: make a copy of the Advanced Channel (or the Media Zone’s playlist channel), then publish that copy to the affected displays. That often clears underlying scripting issues and restores normal item playback.

To help narrow down what’s happening, can you share:

  • Your device type (Chrome OS, Webex Board, SureVue, etc.) and the Appspace app version + firmware version.
  • Whether this happens on all devices or only some, and which channel is assigned.
  • Your platform (web app, iOS, Android) and version.

We may have to log a ticket for this one so our Customer Care team can look deeper into your environment, if we can’t rule out a corrupted channel.

​@Dawn Wayland It was in fact channel corruption. Strange how it was so consistent, but thank you for the solution.
