Playback speed button doesn’t appear on Kaltura videos in Safari on iPad

[Stephhhxo]

I am a student and watch Kaltura videos on my laptop and the playback speed button always appears. However, on the iPad, the playback speed button seems to be replaced with a button with a screen icon that allows me to toggle between the view of my teacher’s screen and his/her webcam. When I watch lectures that do not have a webcam active, the playback speed button will appear again. The playback button disappears if the professor is recording the lecture with their webcam active as well. How can I fix this to make the playback speed button usable in any lecture? Is this something that my professor can fix?
