Button state change not showing on iPad
I am using custom buttons (buttons inserted as images) for navigation in my course rather then using the Player navigation. I have applied states to these images (Normal/Disabled). When viewing on desktop the states show as expected but when I am viewing on iPad (using browser not mobile app) the States don't always show. For example, I have a text button that when pressed will show a text box i created containing narration notes, when these notes are availible the button shows full color (State: Normal) on slides where narration is not available the button shows at reduced color (State: Disabled). When viewing on iPad the button will be disabled BUT will (sometimes) still appear at full color. What I found confusing is that they sometimes do so this can't be an HTML5 limitation. When viewing on desktop I never have this issue so my buttons are using the variables I assigned correctly =-).
Has anyone used custom buttons for navigation with states? Any advice is appreciated.
