Buttons not working on iPhone

I have published an online course with Lectora X, intended for delivery to an iPhone.


When I upload it to the LMS and try it on my PC, all the navigation arrows work perfectly.


However when I try it on my iPhone, some (not all) of the navigation arrows don't work. They are clickable, but no action happens.


I though I might have had text boxes overlaying the buttons, but I checked that. I also made the buttons always on top, but again no luck.


Any ideas?


P.S. I didn't use one of the mobile templates provided by Trivantis. It is my own creation.
