Workaround to push video thumbnail changes (done in JW player dashboard) to the MAZ app.
Because of a technical limitation, thumbnail updates done for videos in the JW Player dashboard can't be read directly by MAZ apps unless a thumbnail change is accompanied by some change in the video metadata.
However, if you need to make changes to only video thumbnails and no other metadata, please write to success@mazsystems.com after making the changes and we will process the thumbnail changes from the backend.
