hi everyone ,

embedded movie in PDF does not play on iPhone & iPad . It only plays if Acrobat reader is installed . How can I fix this ?

The document is fin in indesign, but once exported it requires an acrobat reader .

This works on my iMac, but not on any other devices .

Even on the iMac, the interactive PDF must be opened via acrobat .

If watched by preview it does not work.

Does anyone know hoe to fix this ?

greetings , Sebastian
