We have created and ePub3 accessible file and validated the same using the latest ePub checker but the in the Mac OS voice-over is not working in ADE. The navigation panel is read but when we go to the body content we get the Frame 0 being repeated. Do we need to change anything in the opf metadata to get this working. Any advise on this will be very helpful, thanks in advance.
I don't think this is a capability in ADE.
