For mobile - some slides play long regardless of timline
I have a course that must be mobile enabled. When I play the course on a computer, everything is fine.
When I play the course on an iPad, some slides have a mysterious delay before the end of the slide. It's like the slide suddenly has an extra 20 seconds of dead air between the end of the audio and before the final elements appear on the screen. I have been trying to reduce the animations, adjust the timelines to the correct length but it does no good. Where is the extra time coming from and how do I get rid of it in the .html5 format for mobile?
The extra time appear on some slides with layers and on some without layers. The further and further you get in the course, the delay gets longer and longer as if it's accumulating somehow.
Any bright ideas? I am told that a mobile version is important for this particular audience.
