Re: question for hive-mind viz. Apple error message on valid epub

Re> MP4 but not whatever

Appie could dodge this issue by capturing the error and then providing an
automated built-in OR 3rd party conversion service.

I'm retired. I started out front end (Video Lottery) and then moved on to
the back end.

When I *was* a front end guy not anticipating chaos was a demotion-al
offense.  Anticipating and solving with complexity was better, but frowned
upon.

Anticipating chaos and soiving with a few free clicks was worthy of a back
patting, from the guy the team leader reported to.
