Player just spins in iOS 9.1

I can't think of any correlation between imageDefaultDuration and the ability to play HLS streams. Setting this value doesn't force using the image player, it just specifies how long to show the image when using the image player.
The link I send to the .m3u8 stream that doesn't play on iOS9.2 Safari has no reference to the player anyhow.
I see that the original link (https://kaltura.babyflix.net/tiny/vu6gp) now works on iPhone iOS9.1. Did you change anything other than removing the imageDefaultDuration Flashvar from the UIConf?
