On my phone, I get a big "Share" button right in front of the keynotes video player. It also prevents me from skipping around the video, no way I'm watching all of that. I tried to go into landscape to fix it, qnd I get a black screen asking me to go back to portait mode. I don't know how you can get such basic things so wrong.
