I create very simple ePubs in Indesign CC 2018. When I export them as ePub version 3 they print perfectly from Adobe Digital Editions on a Mac but print as blank pages or spool to postscript indefinitely from Adobe Digital Editions, on a PC, in Windows. When exported in the older version ePub 2.01 they work and print fine on both Mac and Windows. So my question is: why is ePub version 3 an option from Indesign when it isn't fully supported in Adobe Digital Editions on the Windows platform most popular with the user base? Is there a solution/workaround other than reverting to version 2.01?
