#SUP-258 #time 1.5d #comment We discovered that there is a specific problem on chrome, android devices with the preroll shown at the link sent by the client.The problem is that ended event is not fired when the preroll ends. We isolated the problem by creating html5 video tag and saw that the problem exists regardless Kaltura. We found a way to fix it only for chrome android devices by adding fallback when ended event is fired, now it works.
